Right now it is 5:45. The hearing is still in progress, maybe until midnight 1/30/24

In simple words, a full committee markup is an important formal step for a bill to advance to the floor for a vote. In this case, MTG introduced a bill - House Res. 863 in November 2023.

Right now, the committee is debating, amending and voting on the bill. When an amendment is brought up, it's debated by everyone on both sides (republicans and democrats) until they are satisfied then vote on the amendment. So on... it takes time until both sides are satisfied with all amendments they have debated and voted. Then vote on the amended bill. Go or down before it goes to the full floor.

Interesting process. Fun watching how it plays out in person. Luckily deaf people now have an app to convert speech to text. Or watch this proceeding on Cspan with CC on your phone which I am using mine. Fun!
