Members of the United States Senate and House are still receiving paychecks during the government shutdown, though some lawmakers are looking to change that.

Since 1983, Congress’ pay has been funded by a permanent appropriation, and their paychecks aren’t subject to annual renewal. However, at least 20 lawmakers have asked to have their pay withheld.

U.S. Rep. Bryan Steil, R-Wisconsin, Sen. John Kennedy, R-Lousiana, and others are introducing legislation that would eliminate paychecks for senators and representatives during shutdowns.

Members of Congress earn $174,000 annually, while the Speaker of the House earns $223,500 and Senate majority and minority leaders, including South Dakota Sen. John Thune, earn $193,400.

As of 2015, the median net worth of Congress was $1.1 million — 12 times greater than the average U.S. household.

The government has been shut down for 36 days as of Nov. 6, the longest in history.
