A number of House Republicans and other Republican politicians have expressed concern about Trump's tweeting recently, with many advising him to stop.

Wallace added that Trump’s “conduct is so unprecedented."

Wallace said that Trump destroyed the Republican Party and that opposing Trump is not necessarily a partisan issue between Republicans and Democrats.

“It’s a bridge too far for most people I know frankly, to support this president. It’s not about Republican and Democrats.
