 During the 110th Congress, Senator Tom Coburn put holds on a significant number of bills, raising the ire of the leadership and forcing them to package many of the bills with holds into one Omnibus Act (the so-called "Tomnibus") at the beginning of the 111th Congress.Some senators—such as Senators Ron Wyden and Jeff Merkley, both Democrats representing Oregon—have complained that the hold system makes it too easy to block legislation and that the leadership should not honor holds on the floor unless the senator is personally there to object.Throughout the history of the Senate, multiple unsuccessful attempts have been made to abolish this practice.
