House Speaker Mike Johnson (R-LA) could face a series of challenges following the announcement of an agreed-upon top-line spending number for appropriations bills as time winds down to pass the measures.

In a letter sent to members on Sunday, Johnson revealed he and Senate Majority Leader Chuck Schumer (D-NY) had agreed to $1.59 trillion overall for the appropriations bills, with $886 billion set aside for defense spending and $704 billion for nondefense. The top-line number was initially set last year in the Fiscal Responsibility Act.
