And they found new evidence. And unless everything goes very, very fast impeachment delays Trumps scheduled State of the Union, which is the only time they close congress's session and the only time they can be arrested for lesser crimes than felonies/treason by law.  Some think that it would be the most likely time for even felony/treason arrests because:   The President can't be accused of arrests being politically motivated to interfere with what ever business is on the floor/scheduled.      The president could make arrests right before the SOTU: A, he has a captive audience, B. He has almost the whole gov together and the American people together to make his case for why he had to take these steps/reassure the remaining members of gov that there wont be further arrests if possible.      Remember how Pelosi refused to set a date for the last SOTU for months and Trump had to goad her into it?  She seems to be afraid to close the session that he will arrest people.    Or that could just be hogwsh and she just doesnt like to give the president the mic to talk about his accomplishments.
