New York Republicans are determined to push ahead with a formal resolution to expel Rep. George Santos, a Republican representing New York, following the recent addition of new charges and allegations to a federal indictment against him. With the House now open after a three-week speaker stalemate, Santos' colleagues announced last week that they would seek to remove him from Congress, expecting to move forward with the measure as early as this week.

Santos is set to face an arraignment court proceeding on Friday morning at the federal courthouse in Central Islip, New York, regarding the newest charges brought against him by federal prosecutors. The charges include identity theft, making unauthorized charges on his own donors' credit cards, and providing false information to the Federal Election Commission (FEC) about his campaign's financial state.

The expulsion resolution was initially announced by two of Santos' fellow Long Island Republicans, Reps. Anthony D'Esposito and Nick Lalota, who expressed confidence that the measure would gain traction among House members in light of the significant allegations. LaLota confirmed that he is actively seeking co-sponsors for the resolution, anticipating that momentum will quickly build with the reopening of the House floor for business and proceedings.

Rep. Marc Molinaro, who represents a district in New York's Hudson Valley, voiced his support for a timely vote on the expulsion measure, describing Santos as a "liar and a fraud" who has no place in Congress. Rep. Brandon Williams, another New York Republican representing a district near Syracuse, echoed these sentiments, stating that his prediction of Santos facing legal consequences is starting to come true and it is time for him to step down from his position.

In order for an expulsion resolution to pass, it requires a two-thirds vote of the entire House. The resolution does not need to undergo a lengthy committee process before reaching a floor vote, streamlining the potential removal of Santos from Congress.

Meanwhile, the House Ethics Committee has already initiated an investigation into Santos' actions. One New York House Republican shared with CBS News that they anticipate the Ethics Committee will soon release a report regarding their findings.

Despite the mounting accusations, Santos has maintained his innocence and expressed no intention to resign from his House seat. At his initial arraignment proceeding, he pleaded not guilty to the charges and defended himself against allegations involving his donors, stating that he has no motive to harm those who supported him during his campaign.

Prosecutors have also alleged that Santos and his former campaign treasurer, Nancy Marks, submitted falsified financial reports to the FEC, inflating the campaign's fundraising figures to qualify for certain benefits, perks, and support from Republican Party leaders.

As the resolution to expel Santos moves forward in the House, the political future of the embattled congressman hangs in the balance, awaiting a decision by his fellow House members on his removal from office.
