He was already proven a fraud before he took office. The fact it took them this long says how corrupt the Congress is.
Also, there were 114 votes not to remove him. That is huge.
This says nothing but how corrupt the system is.
From wiki:
On January 11, four Republican New York congressmen who had also been elected in 2022— Anthony D'Espisito, Nick LaLota, Nick Longworthy and Brandon Williams —called for Santos to resign. The other two freshman Republican members of Congress from New York, Marc Molinaro and Mike Lawler , followed suit. Joseph Cairo, the chair of the Nassau County Republican Party, also called for Santos to resign, saying that he had "disgraced the House of Representatives, and we do not consider him one of our congresspeople".
Santos refused to resign, and kept the support of Republican House leadership, including former House Speaker Kevin McCarthy , House majority leader Steve Scalise, and Representative Elise Stefanik (the fourth-highest-ranking House Republican), who relied in part on Santos's vote to support their very narrow (four-seat) House majority. McCarthy did not deny Santos committee assignments or impose any penalty on him for the misrepresentations he made during his campaign. Santos was assigned to the committees on small business and science, space, and technology
