House Speaker Kevin McCarthy (R-CA) blasted President Joe Biden's 2024 budget as "completely unserious" minutes after the White House released its plan to the public.

The White House budget is typically considered dead on arrival in Congress, but it carries political importance as a blueprint for the priorities of the current administration. The proposal will take on additional significance this year as Biden and McCarthy engage in a high-stakes standoff over a summer deadline to raise the debt ceiling.

BIDEN PROPOSES NEARLY $7 TRILLION TAX-AND-SPEND BUDGET

McCarthy specifically took aim at $2 trillion in tax hikes proposed under the president's budget, including a tax on earners making more than $400,000 a year to shore up Medicare as well as a 25% minimum tax on billionaires.

"President Biden just delivered his budget to Congress, and it is completely unserious," McCarthy tweeted on Thursday. "He proposes trillions in new taxes that you and your family will pay directly or through higher costs. Mr. President: Washington has a spending problem, NOT a revenue problem."

McCarthy has promised hard-line members of his conference that he will pursue significant spending cuts as part of any deal, while the White House insists on a clean debt limit hike. McCarthy is unwilling to raise taxes in negotiations with Biden and has taken cuts to Medicare and Social Security off the table.

The pledges leave the Republican-led House with limited options as it weighs budget cuts. McCarthy has signaled a willingness to slash military spending but is facing fierce opposition from defense hawks in his conference.

He brought the director of the Congressional Budget Office to brief House lawmakers on Wednesday in a bid to highlight how federal spending is expected to grow over the next 10 years. Speaking to reporters after the briefing, he called on Biden to sit down to address federal spending and blamed him for stalled negotiations.

He reiterated that sentiment in a joint statement released by House GOP leadership that called Biden's budget a "reckless proposal doubling down on the same Far Left spending policies that have led to record inflation and our current debt crisis."

“We must cut wasteful government spending. Our debt is one of the greatest threats to America and the time to address this crisis is now," the statement read. "Yet, President Biden is proposing out of control spending and delaying debt negotiations, following his pattern of shrugging and ignoring when faced with a crisis."

House Minority Leader Hakeem Jeffries (D-NY) dismissed GOP complaints about Biden coming to the table to negotiate.

"If they want to have a conversation, as they're lecturing America, show us your plan. Put it into the public domain. Take your plan out of the witness protection program," he said during a Thursday morning press conference.
