Representative-elect George Santos, a Republican from New York, speaks during the Republican Jewish Coalition (RJC) Annual Leadership Meeting in Las Vegas, Nevada, US, on Saturday, Nov. 19, 2022. Democrats defied political forecasts and historical trends to keep control of the Senate in a win for President Joe Biden, as voters rejected a handful of candidates backed by former President Donald Trump.

Just weeks after aNew York Timesreport found that Rep. George Santos fabricated several key pieces of his backstory, the chair of the Nassau County Republican Committee says there are other lies that have since been unearthed, including that the lawmaker claimed to be a college volleyball “star” at Baruch University, despite never attending the school.

“He said he was a star and that they won the championship and he was a striker,” Joseph Cairo, chair of the committee, said in a press conference Wednesday.

Elsewhere in the press conference, Cairo called on Santos toresign, saying: “George Santos' campaign last year, 2022, was a campaign of deceit, lies, fabrication.”

“He deceived voters. His lies were not mere fibs. He disgraced the House of Representatives … He’s not welcome here at Republican headquarters,” Cairo said.

Republicans in Congress have also called for Santos to resign.Four House Republicans— all from New York, like Santos — released statements on Wednesday saying the freshman lawmaker “does not have the ability to serve here in the House of Representatives.”

A spokesperson for Santos has not responded to PEOPLE’s requests for comment.

In a two-page resumé first given to the Nassau County Republican Committee in 2020, when Santos launched his first bid for U.S. representative (a race he ultimately lost), the 34-year-old claimed “to have graduated in the top 1 percent of his class at Baruch College, earned an M.B.A. at New York University and more than doubled revenue as a project manager at Goldman Sachs,” theTimesreported this week.

But as he admitted last month, Santos did not attend any university — neither for undergraduate nor graduate studies — and did not work at Goldman Sachs, as he had previously asserted.

Two years after his failed 2020 campaign, Santos was elected in November to represent New York’s 3rd Congressional District, flipping a seat red in the process. Reports about the lies — which the lawmaker has deemed “embellishments” — first began to surface weeks later.

And while he’sadmitted to lying aboutsome things, Santos has remained tight-lipped about others, such as the source of his campaign funding.

In financial disclosure documents, Santos said he earned millions of dollars in 2021 and 2022 from a business he started in May 2021.
