'Please let me know how best to arrange pick-up of those materials from your Embassy in Washington, D.C.,' the email continued.
In another email on April 5, 2017, Schiff's aide asked: 'do you know when we might be able to meet your colleagues at the Ukrainian embassy here in Washington, DC to pick up materials?'
Schiff's office did not respond to a request to confirm the emails.
During the call, the pranksters concocted an elaborate story about Trump having a tryst with a Russian glamour model named Olga Buzova after a Miss Universe pageant in 2013, which led to Vladimir Putin obtaining nude photos of the president.
Other individuals they claimed were involved in the scheme included a former Playboy model and Russian journalist named Ksenia Sobchak and Russian pop star Arkadiy Ukupnik.
Buzova 'got compromising materials on Trump after their short relations,' one of the pranksters told Schiff.
'And what's the nature of the Kompromat?' asked Schiff.
'Well, there were pictures of naked Trump,' said the caller.
The pranksters told Schiff that Sobchak was a Russian secret agent and Putin's goddaughter, and claimed she gave the Russian leader the compromising pictures of Trump to use as blackmail.
ron,' said the prankster.
'And do you know what was discussed?' asked Schiff.
The prankster said they 'discussed many things' and used passwords to recognize each other, including 'It rains again on Brighton Beach' and 'The weather is good on Deribasivska.'
Schiff, seeming to have difficulty understanding Deribasivska, the name of a street in Odessa, asked the caller to repeat himself several times.
In fact Weather Is Good on Deribasovskaya, It Rains Again on Brighton Beach is the name of a 1992 Russian-American comedy movie about secret agents, with its title taken from the intentionally absurd passwords they use.
The street has slightly different names in Ukrainian and Russian and the comedian used the Ukrainian version.
Schiff eventually said he would have his staff call the Ukrainian legislator's office later to 'get spellings and more details on this.'
The prankster promised to send the materials, and also offered to have Sobchak and Buzova extradited to the United States 'and you can put them to your special jail Guantanamo.'
'Well, I'll be in touch with the FBI about this,' said Schiff. 'And we'll make arrangements with your staff. I think it probably would be best to provide these materials both to our committee and to the FBI. So we'll make arrangements between my staff and yours on how to facilitate that. And we'll also obviously let the FBI know about Buzova and Sobchak's plans to travel to Ukraine.'
The caller also suggested that Schiff use the passcode 'The weather is good on Deribasivska' the next time he talks to Trump and 'look at how his face will change color.'
'And so those passwords were used with Mr. Trump?' said Schiff.
'Yes, of course,' said the caller.
'We will be back in touch with you through our staff to make arrangements to obtain these materials for our committee and the FBI. I appreciate you reaching out to us,' said Schiff.
The comedians posted the video of the call online with the caption: 'Democratic Senator Adam Schiff believed Russian prankers Lexus and Vovan that Ukrainian intelligence has confirmation that Russian 'scouts' Ksenia Sobchak , Olga Buzova and Arkady Ukupnik collected dirt on US President Donald Trump.'
Adam Schiff: Hi, how are you?
Caller: Hello Mr. Schiff, thank you for your time.
Schiff: Thank you, Chairman. I appreciate the opportunity to speak to you.
Caller: I know that you work for investigation regarding Trump and Russian government.
Caller: We have some important information about it.
Schiff: And that is documented as well in materials you want to provide to us?
Caller: Yes. Could I explain you where we are?
Schiff: Yes of course. But again, I would caution that our Russian friends may be listening to the conversation so I wouldn't share anything over the phone that you wouldn't want them to hear.
Caller: No, I don't think that will impact on our investigation.
Schiff: Yes. Please, go ahead then.
Caller: In November 2013, Mr. Trump visited Moscow, it was competition Miss Universe. There he met with Russian journalist and celebrity Ksenia Sobchak.
Schiff: I'm sorry, can you explain that again? While he was in Moscow in November 2013 he met with a journalist?
Caller: Well, she's poor journalist. But anyway, she became famous because Putin is her godfather.
Schiff: Okay. Putin godfather, okay.
Caller: She also known as the person who provide support for oligarchs. She met with Trump and she brought him one of Russian girl celebrities, Olga Buzova, who's also known as person who's [unintelligible].
Schiff: Okay, and how do you spell her name?
Caller: Olga Buzova.
Schiff: So Olga Buzova is a friend of the reporter?
Caller: Yes, she's a friend of reporter and I think a special agent of Russia Secret Service Ksenia Sobchak.
Schiff: That Sobchak is or Olga is?
Caller: No, Sobchak is [unintelligible]
Schiff: Okay. So Buzova met with Trump in New York at some point after the 2013 Miss Universe.
Caller: Yes, absolutely. And she got compromising materials on Trump after their short relations.
Schiff: Okay. And what's the nature of the Kompromat?
Caller: Well, there were pictures of naked Trump.
Schiff: Okay. And so Putin was made aware of the availability of the comprising material?
Caller: Yes, of course. Buzova shared those materials with Sobchak and Sobchak shared those materials with Putin, because she's the goddaughter of Putin. And Putin decided to press Trump.
Schiff: And the materials you could provide to the committee or to the FBI, would they corroborate this allegation?
Caller: Sure, of course. When they were in Ukraine we got their conversation by the phone where they are discussing those compromising materials. We are ready to provide it.
Schiff: So you have recordings of both Sobchak and Buzova where they are discussing the compromising material on Trump?
Caller: Absolutely, and we also know who was a mediator between Trump and Russian government who met with ex-advisor of Trump, Mr. Flynn. It was Russian singer, very famous singer, Arkadiy Ukupnik, who met with Mr. Flynn on Brighton Beach in Brooklyn in special Russian café Langeron.
Schiff: What's that again?
Caller: Yes, it's on Brighton Beach. It's a Russian district in Brooklyn.
Schiff: And do you know what was discussed?
Caller: They discussed many things. But the most interesting thing is they used a special password for their meetings. When they met each other they said 'The weather is good on Deribasivska.'
Schiff: The weather is good in – where?
Caller: 'The weather is good on Deribasivska.' That is the name of a street in Odessa. Did you hear?
Schiff: Yes, I did. So it's a street in Odessa?
Schiff: And the code word is 'Weather is good on 'Zerabasta'?'
Caller: Deribasivskaya. Deribasivskaya.
Schiff: Okay. And I'll have my staff call up to get spellings and more details on this.
Caller: The next part of their password was, 'It rains again on Brighton Beach.'
Schiff: 'It rains again on Brighton Beach.'
Caller: Yes. On that meeting, Ukupnik told Flynn that all those compromising materials will never be released if Trump will cancel all the Russian sanctions.
Schiff: Okay. Well obviously we would welcome the chance to get copies of those recordings. So we will try to work with the FBI to figure out along with your staff how we can obtain copies of those.
Caller: Of course we will provide you all our copies of all our materials. But I also would like to let you know that Sobchak and Buzova will pretty soon visit our country and we could arrest them and deliver them to your embassy and we also could extradite them to your country and you can put them to your special jail Guantanamo.
Schiff: Well, I'll be in touch with the FBI about this. And we'll make arrangements with your staff. I think it probably would be best to provide these materials both to our committee and to the FBI. So we'll make arrangements between my staff and yours on how to facilitate that. And we'll also obviously let the FBI know about Buzova and Sobchak's plans to travel to Ukraine.
Caller: I also advise you to check all Sobchak's visits in the West because she was in the West very often and suggest you check what she did there actually. And I also would like to look at Russian café on Brighton Beach Langeron and especially on head of Russian Mafia Uncle Mischa.
Schiff: Uncle Mischa? In Brighton Beach?
Caller: Yes, he's the head of Russian mafia. And he's located on that restaurant on Brighton Beach.
Caller: I just want to advise you just to look at them, please.
Rep. Schiff: Alrighty. This was very helpful, I appreciate it. Anything else you wanted to add today?
Caller: Well I hope that my information will be useful for you and your committee. And I also would like to advise you when you or your colleagues will meet with Mr Trump I advise you to tell him first part of the password, 'The weather is good on Deribasivska,' and look at how his face will change color.
Schiff: And so those passwords were used with Mr. Trump?
Caller: Yes, of course.
Rep. Schiff: Okay. Well thank you very much. We will be back in touch with you through our staff to make arrangements to obtain these materials for our committee and the FBI. I appreciate you reaching out to us.
Caller: Well let's be in touch and wait for your response from FBI.
Schiff: Excellent. I'll have them follow up as soon as possible, and I thank you again. Goodbye
