He's been impeached by the _house_ not by the Senate. The US Senate is extremely complicit with the administration. Something the founders did not intend
Upthread is discussing whether the Dems could flip the necessary seats to impeach and convict.
(And no, there is no way they will. It would take winning 20 out of the 22 seats, and losing none, assuming a party-line vote w/ independents siding with Dems. That won't happen. Also, the required vote in the Senate is two-thirds, not "60".)
