The Senate has decided that the second impeachment of Donald Trump is constitutional and voted to proceed with impeachment.

Six GOP Senators joined Democrats in voting to proceed.

According to CNBC:

The Senate voted that it has jurisdiction under the Constitution to hold former President Donald Trump’s impeachment trial.

The 56-44 vote came after House impeachment managers and Trump’s defense team spent four hours making arguments on whether a president can be subject to a Senate trial after leaving office.

“The senate shall proceed with the trial,” said Sen. Patrick Leahy, D-Vt., who is presiding over the trial, after the vote was tallied.

Sen. Bill Cassidy of Louisiana, one of six Republicans who joined all 50 Democrats in voting to hold the trial, was the only senator to change his vote from the last time the question had been posed to the chamber weeks earlier.

The six Republicans who sided with the Democrats were: Sens. Susan Collins of Maine, Bill Cassidy of Louisiana, Lisa Murkowski of Alaska, Mitt Romney of Utah, Ben Sasse of Nebraska, and Pat Toomey of Pennsylvania.
