WASHINGTON (AP) – Republican senators have blocked a bill to keep the U.S. government funded and allow borrowing. But Democrats determined to avoid a federal shutdown say they will try again this week. All this as Democrats also press ahead on President Joe Biden’s big domestic policy agenda. The tangled efforts Monday are not necessarily linked. But the fiscal year-end deadline to fund government operations past Thursday is up against the Democrats’ desire to make progress on Biden’s $3.5 trillion federal government overhaul. Republicans reject Biden’s package as too big. And they won’t vote for more borrowing to pay past debts.
