There's lots of questions currently about how the House elects its Speaker and what happens when it can't, and it's generally accepted that the House can't actually do anything else until a Speaker is chosen - the US Code (in Title 2 Chapter 2 § 25) explicitly forbids taking up any other business:
At the first session of Congress after every general election of Representatives, the oath of office shall be administered by any Member of the House of Representatives to the Speaker; and by the Speaker to all the Members and Delegates present, and to the Clerk, previous to entering on any other business;
However, there are obviously things that it can still do, such as voting to adjourn for the day.
What, specifically, is the House able to do? I expect that the answer is mostly going to be procedural motions, but what are the details, or where is it spelled out?
Some specifics:
- Can they vote to recess, or are they and the Senate stuck in session?
- Is there any kind of notice or priority event that they could switch to? (Someone suggested in a comment that the notice of the Senate passing a bill might qualify.)
- How can they change the rules to the vote for Speaker if there aren't any rules adopted yet?
