Rep. George Santos, R-N.Y., named himself treasurer of his re-election campaign in a new filing with the Federal Election Commission late Friday afternoon. The new filing comes a little over a week after the congressman pled not guilty to federal charges. 

Santos now becomes the fourth treasurer of his campaign and committees since January. He had previously filed paperwork naming Andrew Olson treasurer of the campaign, following the departure of his longtime treasurer Nancy Marks amid a number of controversies surrounding the fundraising and spending of his campaign money. 

Olson's name is now notably absent from the filings; however, the email address "apolson1964@gmail.com" is still listed along with a Washington, D.C., PO box. 

Fox News Digital reached out to Santos' office for comment but did not immediately hear back.

Santos tweeted out Saturday in regards to the new filings, writing "On Friday, May 19, I was properly notified by my campaign’s then Treasurer, Mr. Andrew Olson, of his resignation. I appreciate the work Andrew and his team have done for the campaign and appreciate his willingness to ensure a smooth transition."

"To ensure compliance, upon the resignation, I was named as Treasurer. A treasurer must be appointed within ten (10) days of the resignation of the previous treasurer," he continued.

"My intent is to operate above reproach. We will continue to build our campaign around professionals with subject matter expertise. I have retained the professional services of a new Treasurer to ensure the campaign moves forward in compliance. FEC records will reflect the update," Santos closed. 

HOUSE GOP LEADERS REACT TO SANTOS INDICTMENT: 'THERE IS A LEGAL PROCESS'

The new filings come a little over a week after Santos pled not guilty to federal charges, hours after a 13-count indictment was unsealed against him.

The indictment was made public in the U.S. District Court for the Eastern District of New York and charged the congressman with seven counts of wire fraud, three counts of money laundering, one count of theft of public funds and two counts of making false statements to the House of Representatives.

Just two days prior to the new filings being made, House Republicans blocked an effort by Democrats to expel the embattled congressman in a party-line vote that referred the matter to the House Ethics Committee.

The expulsion resolution, which was initially introduced by Rep. Robert Garcia, D-Calif., in February, had seven Democrats, including all five on the Ethics Committee, vote present, with Republicans making up all the yes votes and Democrats all the no votes.

"You cannot behave as judge and jury in this procedure. I thank leadership for allowing this procedure. Quite frankly there were seven Democrats who agreed and voted present on this procedure," Santos said on the vote.  (Tom Williams/CQ-Roll Call, Inc via Getty Images)

Santos later responded to the vote, telling reporters on Capitol Hill "everybody is innocent until proven guilty."

"You cannot behave as judge and jury in this procedure. I thank leadership for allowing this procedure. Quite frankly there were seven Democrats who agreed and voted present on this procedure," Santos said. 

The embattled congressman has come under fire for allegedly fabricating large parts of his résumé after flipping New York's 3rd Congressional seat last year, with his victory partly due to his inspirational backstory which he now admits was largely fictitious.
