As hopes faded Friday for a quick end to the shutdown — with Democrats holding firm in a key Senate vote — the White House signaled more layoffs and agency cuts could follow. Democrats have seized on the shutdown and cuts as evidence of Trump’s overreach. Democratic candidates in both states have linked their GOP opponents to Trump’s policies and criticized them for not standing up to his latest moves. The cuts are also complicating Senate negotiations, prolonging a shutdown that could leave thousands of federal workers without pay and halt key programs. Sen. Angus King, a Maine independent, broke from Democrats earlier this week to support the GOP funding bill.
