Dozens of House Republicans are already raising objections to keeping huge swaths of the federal government from shutting down before the legislation has even been released.

Why it matters: It places new pressure on House Speaker Mike Johnson (R-La.) to capitulate to conservative demands as negotiators try to hammer out agreements on outstanding issues.

• Agencies covered by the bill are set to shut down on Friday if the legislation isn't passed.

Driving the news: In a letter to their GOP colleagues, a group of 43 House Republicans called to reject spending legislation that doesn't include sweeping GOP border legislation and a rollback of diversity and climate policies at the Pentagon.

• "These policies are intentional and rooted in radical progressive Democrats' desire to fundamentally remake America. A vote to fund this government without policy reforms is a vote for these policies," they wrote.
• The bill is expected to include funding for the Departments of Homeland Security, State, Defense and Health and Human Services.

Zoom in: The letter is led by Reps. Bob Good (R-Va.), chair of the right-wing Freedom Caucus, and Chip Roy (R-Texas), a prominent member of the group.

• Most of its signers are Freedom Caucus members, but several are not — including Reps. Jim Banks (R-Ind.), Kat Cammack (R-Fla.), Rich McCormick (R-Ga.), William Timmons (R-S.C.) and Nancy Mace (R-S.C.).

Between the lines: Johnson has been able to shepherd major spending legislation through the House through a process that bypasses party-line procedural votes but requires a bipartisan, two-thirds majority to pass bills.

• That has effectively allowed him to do an end-run around the right-wing hardliners who spend last year stymying GOP legislation.
• Johnson's right flank still holds one card — the ability to force a vote on removing him as speaker — but has so far proven reluctant to use it.
