(WASHINGTON) — President Donald Trump’s proposal to reopen the government, sweetened with immigration provisions aimed at mollifying Democrats but which have alienated some conservatives, is headed for Senate action, its prospects uncertain. Senate Majority Leader Mitch McConnell will try to muscle through the 1,300-page spending measure, which includes $5.7 billion to fund Trump’s proposed wall along the U.S.-Mexico border, the sticking point in the standoff between Trump and Democrats that has led to a partial government shutdown now in its 32nd day. Meanwhile, another missed paycheck looms for hundreds of thousands of federal workers. Senate Republicans late Monday unveiled the legislation, dubbed the “End The Shutdown And Secure The Border Act,” but its passage this week is by no means certain. Republicans hold a 53-47 majority in the chamber but need Democrats to reach the usual 60-vote threshold for bills to advance.
