Democrats can "forget about unity" if they continue to push for an impeachment trial in the U.S. Senate of former President Donald Trump, ex-White House trade adviser Peter Navarro said Wednesday.

"That's gone, that's off the table," the 71-year-old Navarro, a Democrat turned Republican economist, said on the "War Room" podcast on Wednesday. "This will be a 50–50 country. The gap between us will be a chasm. There will be nothing but friction."

If Biden is unable, or unwilling, to persuade Congressional Democrats "from backing down from trying to gut Donald J. Trump, forget about unity," Navarro added.

Despite Biden's weeks long call for "unity," the Democratically controlled House of Representatives impeached Trump on Jan. 13 claiming that he incited an "insurrection" a week earlier by encouraging his supporters at a rally to march "peacefully" to the U.S. Capitol. Several hundred people breached the Capitol building while the Congress was debating certification of the Electoral College vote.
