“It’s not a good way to start the new Congress in its relationship with the Foreign Relations Committee,” said Sen. Marco Rubio of Florida, a Republican on that panel, in an interview. “It violates the law. And the law is clear about those timelines. I’m urging them and I expect them to comply with the law.”

Sen. Cory Gardner of Colorado, a vulnerable Republican who faces re-election in 2020, said “the administration needs to submit the report,” adding: “There’s no excuse. They must submit it.”
