A roughly $70 billion bill to fund immigration enforcement through the remainder of President Donald Trump’s term was supposed to be an easy lift for Republicans.

But progress stalled over concerns about the inclusion of White House ballroom security funding in the package and the creation of a $1.8 billion fund to finance claims of government mistreatment. The stumble has not only delayed action on a top GOP priority but also is raising questions about other parts of the party’s legislative agenda, including whether Republicans can enact another catchall, party-line bill referred to in Washington parlance as “Reconciliation 3.0.”

Republicans have spent recent weeks laying the groundwork for such a bill, which they hope will serve as a final sales pitch to voters going into the midterms.

Speaker Mike Johnson and Majority Leader Steve Scalise, both of Louisiana, have been meeting with committee and caucus chairs to screen for proposals that have strong buy-in from the rank and file. They are aiming to follow up on last summer’s big tax and spending cuts bill with a measure that would increase Pentagon spending by hundreds of billions of dollars and would include cuts elsewhere to help pay for it, which they are couching as tackling government waste and fraud.
