Trump urged Senate Republicans on Sunday to overrule the chamber’s parliamentarian in order to pass key parts of his sweeping domestic policy bill.

In a Sunday post on Truth Social, the president backed a call from Rep. Greg Steube (R-Fla.) and other GOP hard-liners to ignore rulings from Senate Parliamentarian Elizabeth MacDonough.

The parliamentarian is the nonpartisan Senate official responsible for determining whether parts of laws meant to be passed through budget reconciliation comply with the rules for that process.
