After deadly Capitol riot, Trump impeachment trial to open with fight on Constitution | Reuters

Trump s lawyers plan to open the trial on Tuesday by questioning whether the U.S. Constitution allows the Senate to hold an impeachment trial for a president after he has left office.

Most Senate Republicans have embraced that argument, which strongly suggests that Democrats will be unable to garner the two-thirds majority needed to convict in the 100-member Senate. Democrats and many legal scholars reject the Republicans constitutional interpretation.

Thank goodness for legal scholars. Without them, you would suspect the Democrats were just being partisan.
