'I'm currently a no': Marjorie Taylor Greene reveals why she now opposes Trump's big bill

One of President Donald Trump's most stalwart supporters in Congress is now threatening to tank H.R. 1 — the "One Big Beautiful Bill Act" — due to changes made in the Republican-controlled Senate.

In a post to her X account on Thursday, the far-right Georgia Republican said that while she remains committed to many of the bill's provisions and to passing Trump's legislative agenda through Congress, she is opposed to the bill in its current form. Greene blamed the "far left Senate parliamentarian" for "stripping out many of our good provisions" along with "the special interest lobbyists sneaking in dirty poison pills" like a 10-year ban on states passing regulations on the artificial intelligence (AI) industry for her newfound opposition to H.R. 1.

"I’m currently a NO," Greene posted. "We need to pass President Trump’s GREAT tax promises! We need to pass President Trump’s GREAT energy plan! And we need to fund President Trump’s GREAT Border Patrol and ICE! But we do not need to pass a One Big Beautiful Bill that continues to fund sex changes on kids, Medicare and Medicaid for illegals, and destroys federalism!!!"

The MAGA firebrand called on Senate Majority Leader John Thune (R-S.D.) to "fire the Senate Parliamentarian" and "strip out the 10 year AI moratorium" in order to change her "no" vote to a "yes" vote. However, Thune already said on Thursday that he would not fire Senate Parliamentarian Elizabeth MacDonough, saying that doing so would "not be a good outcome."

The "good provisions" Greene said were removed by MacDonough's hand include removal of language capping states' use of health provider taxes to get more matching federal funds. She also stripped out a section of the bill shifting some of the costs the federal government pays for the Supplemental Nutrition Assistance Program (SNAP, or food stamps) to states – which would be the first time in history states would be on the hook to cover food stamp funding.

H.R. 1's fate in the Senate remains unknown, despite Republicans having a typically reliable 53-47 majority in the body. Thune can only afford three defections from the Senate Republican Conference if he hopes to send the bill back to the House of Representatives with a tie-breaking vote from Vice President JD Vance.

Moderate Senate Republicans like Susan Collins (R-Maine) and Lisa Murkowski (R-Alaska) have expressed concerns over the bill's cuts to Medicaid,, in addition to Sen. Josh Hawley (R-Mo.), whose state has a high percentage of residents who rely on the program for health insurance. Sens. Ron Johnson (R-Wisc.) and Rand Paul (R-Ky.) have also said they oppose the bill, with Johnson calling for harsher spending cuts and Paul opposing the bill's increase of the borrowing limit.
