A bipartisan bloc of House Judiciary Committee leaders have agreed to demand new limits on the National Security Agency’s warrantless surveillance program as a condition of temporarily extending its authorization, setting up a fight with the Trump administration.

As part of an extension, they also have agreed to push for restrictions on surveillance. Among them is a requirement that F.B.I. agents obtain warrants before searching the program’s repository of intercepted messages for information about American criminal suspects. And they want to ban a disputed form of internet surveillance in which the agency collected emails that were about a foreign target of surveillance but neither to nor from that person; the N.S.A. voluntarily ceased that form of surveillance this year but wants to retain the flexibility to turn it back on again.
