Two lawmakers introduced a bill this week that requires stricter reporting of political donors to the Federal Election Commission, a response to the U.S. Supreme Court decision this week striking limits on aggregate campaign contributions.

Rep. Beto O’Rourke, D-Texas, filed the Real Time Reporting and Transparency Act in the House on Thursday, and Sen. Angus King, I-Maine, filed a companion bill in the Senate. The legislation would require political committees to notify the FEC within two days when a contributor cumulatively gives more than $1,000 in a calendar year.
