democracy protection package, was just published, yesterday or day before I think. Don't know about all those things, but for sure tax returns are in there, amaf 10 years' worth. The first article below is pre-publication but explains it in general.
House Democrats officially unveil their first bill in the majority: a sweeping anti-corruption proposal: Democrats will take up voting rights, campaign finance reform, and a lobbying crackdown all in their first bill of the year.

Also from Vox, yesterday: Lobbyists are already mounting an opposition strategy to Democrats anti-corruption bill: HR 1 is meant to crack down on money in politics. Conservatives and lobbying groups are calling it a threat to free speech.

Of course, the Republicans still control the senate. But Democratic control of the house means their passing new legislation that further institutionalizes their power and corruption has been halted. So the Republicans have shifted to fast-tracking institutionalizing corruption through court appointments, which only gaining a Democratic majority in 2020 will stop.
