A divided Senate voted 56 to 44 on Tuesday to proceed with the impeachment trial of former president Donald Trump, rejecting his lawyers’ argument that it is unconstitutional

Most Republicans stood with Trump and his legal team, which contended the Senate cannot convict a person no longer in office. The House impeachment managers, in pressing for the trial to proceed, said Trump had a role in inciting the deadly Jan. 6 attack on the Capitol and should be held accountable. Opening arguments in the trial are set to begin Wednesday.

Here’s what to know:

  • The Senate voted 89 to 11 to agree to the rules of the trial. All 11 votes against the rules came from Republicans.
