"I think I'm going to be able to get along with Pelosi — I've always had a good relationship with Nancy Pelosi," Trump said Tuesday on MSNBC's "Morning Joe," referring to the House minority leader.

Trump argues that the Texas senator won't work with others in Congress and that while both candidates have positioned themselves as political outsiders, Trump argues even Republicans don't want Cruz.

"He is a guy that nobody likes and nobody trusts," Trump said on MSNBC before reiterating that Cruz "is a nasty guy, he says things that are very nasty, so I have to be nastier than him and it's just one of those things."

"I've been in politics all my life, I've been dealing with politicians all my life," Trump said of whether he would have any friends in Congress.

The pivot to stress his ability to work with Democrats in Congress comes as Trump continues to dominate in polls nationally and in New Hampshire, which hosts its primary Feb. 9, eight days after Iowa.

Trump has argued that establishment Republicans are warming to his potential presidency because they are scared of Cruz getting into the White House.

Still, Trump was thrown on the defensive Tuesday by a pair of Cruz's ads released in the past week hitting Trump on eminent domain and bashing the businessman for calling the people of Iowa "stupid."

"He's just saying lie after lie, it's not becoming," Trump said on ABC's "Good Morning America."

During that interview, when pressed on whether one could assume Trump would show up at the Fox News debate Thursday night, Trump told ABC, "You can probably make that assumption, but I'm thinking about it."

During the MSNBC interview, Trump also teased rolling out a "very powerful endorsement" Tuesday. He was backed by 2008 Republican vice presidential candidate Sarah Palin last week and "Duck Dynasty" star Willie Robertson.
