MSNBC analyst lays out the 'genuinely sick thing' about Trump's Republican defenders

Is President Trump's "witch hunt" argument winning?

Don't be so sure it's not, points out MSNBC analyst John Heilemann. Trump's historically bad approval ratingsare up, and Heilemann thinks that trend can continue as long as Robert Mueller is remaining silent and Republican officials are standing by Trump.

He points out that some Republicans now want to re-open the guilty plea by disgraced former National Security Adviser Michael Flynn.

"The genuinely sick thing about what's happening right now is the number of enablers the president has right now among people who used to be sober, responsible people," Heilemann said.

This is a problem because Mueller has to remain silent as he investigates, all while Trump spins and spins.

"He's got a loud, big 'Amen' chorus that's going to be singing this song that he's been singing," Heilmann said. "We may have gotten through this day... but we are headed toward a bigger confrontation."

What will the Republicans do if evidence of Trump's collusion with Russia, or an equally bad crime, comes out? He's not sure.

"There's going to be a moment when this whole thing blows up and I don't think it's far off now," he said.
