Senate hold

In the United States Senate, a hold is a parliamentary procedure permitted by the Standing Rules of the United States Senate which allows one or more Senators to prevent a motion from reaching a vote on the Senate floor, as no motion may be brought for consideration on the Senate floor without unanimous consent.

If the Senator provides notice privately to their party leadership of their intent (and the party leadership agrees), then the hold is known as a secret or anonymous hold. If the Senator objects on the Senate floor or the hold is publicly revealed, then the hold is more generally known as a Senatorial hold.
