U.S. Senate negotiators on February 2 reached a deal on a proposal to overhaul the asylum system at the U.S. border with Mexico, clearing the way for Democratic and Republican Senate leaders to begin the difficult task of convincing Congress to pass a national-security package that will include tens of billions of dollars for Ukraine and immigration enforcement, as well as funding for Israel and other U.S. allies. Senator Chris Murphy, lead Democratic negotiator, said on social media that a deal had been reached and that text of the bill would be released over the weekend.
