Senate Republicans' Threat to Block Border Security Bill Raises Compromise Concerns

Senate Republicans are threatening to block a bipartisan package of border security measures and asylum restrictions, just one day after their chief negotiator signed off on it. The GOP senators are seeking more time to discuss changes to the bill in the form of amendments, and their opposition could be devastating to the package, which is now backed by President Joe Biden. Donald Trump is demanding that Republicans sink the agreement, using immigration as a political weapon in the fall election, while House Republican leaders have already declared the bill "dead on arrival" in the lower chamber.
