Santos has lied about everything from where he went to college to his Jewish ancestry. He is being investigated by local, state and federal authorities. He told reporters on Capitol Hill Wednesday that he does not plan to resign.

The Nassau County Republican Party made the rebuke official later Wednesday at its headquarters in Westbury, New York.

The same day, Speaker kevin mccarthy he told reporters he would not seat Santos on any of the so-called «A Committees,» including more powerful panels like the Judiciary, Ways and Means and Budget, which usually don’t go to first-term lawmakers anyway. It is not yet clear if Santos will sit on the committees, as some of his fellow Republicans have called for him to be excluded from panel seats entirely.

McCarthy and other House Republican leaders have yet to publicly signal how they plan to handle Santos fabrications internally.
