House committee assignments once were the seat of power. Do they matter anymore?

House Democrats celebrated in early February when they successfully removed Republican Representative Marjorie Taylor Greene from her committee assignments. It was a move they thought would neutralize the freshman congresswoman who promoted conspiracy theories about mass shootings and the government when she was a candidate. 

But Greene, who also spread falsehoods about the 2020 election, saw an opportunity.  "I woke up early this morning literally laughing thinking about what a bunch of morons the Democrats (+11) are for giving someone like me free time," Greene tweeted the following day.
