The House gavels in at 9 a.m. EST and the full chamber will vote to confirm the rules they made yesterday.
After that, Republicans will yell a lot (hello, Doug Collins!) and try various parliamentary procedures to drag out the process. The votes on the two articles of impeachment — are expected in the late afternoon, probably between 4 and 6 p.m. The House votes on each of the two articles.
Expect plenty of theatrics as Republicans throw themselves on the tracks in front of the impeachment train.
