THE SUPER BOWL SHOWDOWN between the Kansas City Chiefs and Philadelphia Eagles won’t be the only action at the Caesars Superdome in New Orleans on Sunday.

President Trump and Speaker Mike Johnson (R-La.) will attend the game together, as House Republicans squabble over spending and the Senate GOP tries to grab the steering wheel away from Johnson.

It’s a high-stakes, intra-party battle for control, with Trump’s legislative agenda hanging in the balance.

It begins tonight. Senate Republicans are headed to Mar-a-Lago to huddle with Trump. House Republicans will work through the weekend — including on Super Bowl Sunday — as they seek to maintain control of the process.

Additional details could be revealed in Trump’s interview with Fox News Channel’s Bret Baier, which will air during the game.

Here’s the latest:

• Johnson and House Republicans were supposed to have already released a blueprint for “one big, beautiful” bill that extends Trump’s tax cuts, addresses the debt ceiling and allocates new spending for Trump’s priorities, including border security.

But conservative fiscal hawks want to see trillions more in cuts than Johnson is offering, citing the national debt as their primary concern.

The extension of the Trump tax cuts would reduce government revenue by somewhere in the neighborhood of $1 trillion annually, according to the Committee for a Responsible Federal Budget.

Johnson says House Republicans made some progress Thursday at a five-hour closed door meeting. He says the House blueprint could come Sunday or Monday.

Johnson blamed Democrats for the stalemate, eliciting outrage from Democratic leaders who say they've been trying to get Republicans to negotiate for weeks.

"He’s full of s‑‑‑," said Rep. Jim McGovern (D-Mass.).

Senate Republicans are tired of waiting, with the clock ticking toward a March 14 government shutdown.

While the budget traditionally originates in the House, Senate Budget Committee Chair Lindsey Graham (R-S.C.) says the upper chamber will take the lead on a two-bill strategy.

Graham unveiled a 61-page budget resolution on Friday and planned a mark-up for next week.

The Hill's Alexander Bolton has the details: "The resolution includes $175 billion to secure the southern border and $150 billion to beef up national defense...If the Senate and House adopt the resolution...it would allow Senate Majority Leader John Thune (R-S.D.) to bring a reconciliation package to the Senate floor... immune from a Democratic filibuster."

GOP senators will press Trump to side with them when they huddle with the president at Mar-a-Lago this evening.

Johnson is feeling the squeeze.

“Our message to our friends and colleagues in the Senate is: Allow the House to do its work,” he said.

The Hill’s Mychael Schnell reported Johnson said he’s been playing “phone tag” with Graham for the last 36 hours.

“I sent him a text message earlier this morning and explained where we are in the process and how it’s moving aggressively and how important it is for the House to be the one that leads on this and so I expect I’ll talk with him today,” Johnson said.
