Washington (CNN) Senate Majority Leader Mitch McConnell on Thursday night shrugged off outrage over President Donald Trump's willingness to receive foreign dirt on political opponents, chalking it up to partisan bitterness over the 2016 election.

Ingraham also asked, "Do you think the President made a mistake in the way he answered that question when he said, 'Maybe I would, maybe I wouldn't. I would hear them out.' Would you answer the question that way?"
