If those are not met, Democrats say they are prepared to block the wide-ranging spending bill, denying Republicans the votes they need to pass it and triggering a shutdown at midnight on Friday.

"There has to be accountability.”Amid the administration’s immigration crackdown, Schumer said Democrats are asking the White House to “end roving patrols” in cities and coordinate with local law enforcement on immigration arrests, including requiring tighter rules for warrants. Democrats also want an enforceable code of conduct so agents are held accountable when they violate rules. Senate Majority Leader John Thune, R-S.D., has indicated that he might be open to considering some of the Democrats' demands, but he encouraged Democrats and the White House to talk and find agreement.
