“Every word I said there is true and accurate. No one disputed a word I said,” Cruz said during an MSNBC town hall in Buffalo, N.Y.

Cruz raised eyebrows last year when he accused McConnell of lying about a deal to move the Export-Import Bank reauthorization in exchange for support on fast-track trade legislation.

He said at the time that McConnell had told him in a private conversation that there wasn't a deal.

"Well, we now know that when the majority leader looks us in the eyes and makes an explicit commitment, that he is willing to say things that he knows are false," he said at the time.

The blistering floor speech sparked fierce backlash from his Republican colleagues, some of whom questioned if Cruz had broken Senate rules with his speech.

The Texas senator defended his actions on Thursday.

"The reaction in the Senate is, 'How dare you say that out loud?' They’re not upset that somebody lied to them,” he said.

Cruz isn't a stranger to antagonizing his Republican colleagues, who are still quick to cite his role in the 2013 shutdown of the federal government.

Cruz, however, brushed aside the notion that he wouldn't be able to work with a Republican-controlled Congress if he wins the White House.

“I think I’ll be able to work very, very well with Republican leadership, partially for focusing on issues that bring us together,” he said during the MSNBC town hall.
