Embattled New York Republican George Santos says he won’t serve on the two House committees he was assigned to, pending investigations into the many lies and unanswered questions around his life and finances. Santos shared the news after a private meeting Monday with Speaker Kevin McCarthy. It comes as McCarthy is pushing to remove influential Democrat Ilhan Omar from the House Committee on Foreign Affairs.

Meanwhile, Santos’s treasurer has resigned amid intense scrutiny over his campaign funding, including the source of at least $625,000 that Santos had previously claimed were personal loans. Last week, Mother Jones reported many people listed as top donors to Santos’s campaign don’t appear to exist.
