Rep. Elijah Cummings, D-Md., said Thursday he is still trying to determine if Michael Cohen lied to Congress again last week, an act for which the chairman of the House Oversight Committee vowed to "nail [Cohen] to the cross" if it happened.

Speaking with CNN on Capitol Hill, Cummings — whose panel hosted Cohen for more than six hours Feb. 27 — indicated he needs to ascertain if Cohen lied when he claimed he did not seek a pardon from President Donald Trump. Cohen's lawyer admitted this week the pardon issue was raised.

"I told him, 'I will nail you to the cross [if you lie].' And I meant that," Cummings said. "I gotta make sure they are true inconsistencies and not outright lies. And then I gotta find out if it meets even the threshold that the DOJ would even want to look at it."

Cohen was asked during his testimony in front of the committee if he sought a pardon from Trump, to which he replied no. The former Trump lawyer, who is slated to serve a three-year sentence starting in May for lying to Congress and tax and bank fraud, has also come under fire for saying he did not want a White House job and was disillusioned when he never got an offer for one.
