'Trial of Former President Is Found Constitutional, With 6 G.O.P. Votes'
'The Senate voted on Tuesday to proceed with the impeachment trial of former President Donald J. Trump, rejecting his defense team’s claim that it would be unconstitutional to prosecute a president after leaving office. But the final tally signaled that his Republican allies could muster enough support to potentially block the two-thirds necessary for conviction.
The 56-to-44 vote, with six Republicans joining all 50 Democrats, paved the way for the House Democrats trying the case to formally open their arguments on Wednesday afternoon as they seek to prove that Mr. Trump incited an insurrection by encouraging supporters who stormed the Capitol last month and disrupted the counting of Electoral College votes.
But the 44 Republicans who agreed with Mr. Trump’s claim that a former president cannot be subject to an impeachment trial seemed to all but guarantee that he would have the 34 votes he needs on the final verdict to avoid conviction. To succeed, the House managers would need to persuade at least 11 Republican senators to find Mr. Trump guilty in a trial that they have deemed unconstitutional.'

The Supreme Court has no saying in this?
