More information has been released detailing the steps some lawmakers took to donate part of their pay after last year's government shutdown.

The Washington Post reported last week how hundreds of lawmakers donated more than $490,000 either to charity or back to the U.S. Treasury to help pay down the federal deficit in the weeks after the 16-day federal government shutdown in October. After The Post published its report, about a dozen more members responded with details of their payments.

Over the weekend, two more lawmakers not originally listed confirmed that they also made donations.

Rep. Trey Gowdy (R-S.C.) sent donations of an undisclosed sum to First Baptist Church, in Spartanburg; SAFE Homes Rape Crisis; and the Children's Advocacy Center in Spartanburg, Cherokee and Union counties, a spokesman said Sunday. And Rep. Chris Gibson (R-N.Y.) donated $5,400 to a Catholic Charities food pantry, a spokeswoman said.

The House chief administrative officer late Friday also released its fourth-quarter Statement of Disbursements, a quarterly accounting of the House's quarterly expenses and revenue. The document lists lawmakers who decided to send portions of their salary or House office budget to the Treasury during that period.

The document confirms donations from several lawmakers who told The Post that they sent money to the Treasury: Reps. Jim Costa (D-Calif.), Tulsi Gabbard (D-Hawaii), Phil Gingrey (R-Ga.), Ralph M. Hall (R-Tex.), Frank A. LoBiondo (R-N.J.), Markwayne Mullin (R-Okla.), Bill Posey (R-Fla.), Jason Smith (R-Mo.) and Niki Tsongas (D-Mass.). (See their donations here.)

But the document also lists names not included in The Post's original tally. First, it reports that Gabbard donated $4,547.27 to the Treasury. Her office had declined to report the amount. Here are the other names:

Rep. Spencer Bachus (R-Ala.): $414.39

Rep. Steven Pearce (R-N.M.): $6,283.99

Rep. Tim Walz (D-Minn.): $2,196

Rep. Christopher P. Gibson (R-N.Y.): $17,140.40

Rep. Scott Rigell (R-Va.): $6,525.00

A spokesman for Pearce confirmed that his donation was in response to the shutdown. Walz donates the balance of a congressional pay raise that began in 2009. He also donated money to Minnesota food banks after the shutdown. Gibson's donation to the Treasury also is unrelated to the shutdown. He is a U.S. military veteran and donates the cost of his military pension back to the Treasury, an amount totaling about $50,000 annually, a spokeswoman said. Rigell, one of the wealthier members of Congress, regularly donates portions of his salary to the Treasury. He also donated $6,485 to the Wounded Warrior Project after the shutdown.

A spokesman for Bachus didn't immediately return requests for comment.

Three House lawmakers who told The Post that they sent money to the Treasury, Rep. Suzan DelBene (D-Wash.), Jared Polis (D-Colo.) and Brad Schneider (D-Ill.), were not listed on the Statement of Disbursements. That's because they wrote personal checks to the Treasury instead of sending the money through the House CAO, according to copies of receipts provided by their offices to The Post.

Unlike the House, the Senate does not release a document similar to the Statement of Disbursements. Three senators -- Christopher A. Coons (D-Del.), Mike Enzi (R-Wyo.) and Ronald H. Johnson (R-Wis.) -- told The Post that they donated money to the Treasury.
