WHITE HOUSE: Senate override of 9/11 bill veto 'most embarrassing thing' lawmakers have done in decades
It's "the single most embarrassing thing the United States Senate has done possibly since 1983," he told reporters after news of the Senate's 97-1 vote broke earlier in the day.
It was not immediately clear what Earnest was referencing from 1983 and a White House spokesman didn't immediately respond to a request for clarification.
The override attempt now goes to the House for a vote, where it is expected to pass. If passed, the legislation becomes law.
President Barack Obama vetoed the bill last week.
