David is correct here. The Republicans desperately want to turn this markup session into a long, boring circus. They’ve come armed with about 150 amendments, dozens of which will come to a vote, almost all of which will be defeated. Here, via Hill Heat, are just a few doozies:

Vitter proposed 14 amendments:

Amendments #23-#28 are pro-nuclear. Amendment #32 increases the auction percentage to 100% by 2029. Amendment #38 overrides the Massachusetts vs. EPA decision.
