Article 1Section 3 : The Senate shall try ALL impeachments
Even mo' better, Art. 2, Sec. 3 says:
"...he [the prez] may, on extraordinary occasions, convene both houses, or either of them...."
Let Nancy end the session, then Trump can call the House back into session and make them stay there until Nancy coughs up the articles of impeachment. Ain't the Constitution grand (when it's faithfully applied)?
