Just last week, Democratic Sen. Mary Landrieu argued during a Capitol Hill hearing that the government needs more tax revenue.

But in a twist of hypocrisy, the Louisiana senator and her husband appear to have not yet paid $1,206.95 in tax penalties to the District of Columbia government on their Capitol Hill home, The Daily Caller has learned.

According to public records available online in the District of Columbia’s “Real Property Assessment Database,” the D.C. government has penalized Landrieu $1,003.33, plus $202.62 in interest, for 2012 taxes on her mansion on East Capitol Street. It is unclear what the penalty is for.
