On Capitol Hill, House lawmakers approved a bill Thursday to expand background checks for firearms purchases from three to 10 days. The bill would close what’s been dubbed the “Charleston loophole,” under which white supremacist Dylann Roof was able to purchase a gun used to massacre nine worshipers at the Emanuel AME Church in Charleston, South Carolina.

Thursday’s vote followed another gun control bill approved Wednesday to strengthen federal background checks. That bill came under fire from immigrant rights groups after some Democrats defected and helped approve a last-minute amendment offered by Republicans that would require Immigration and Customs Enforcement officials be notified any time an undocumented immigrant tries to buy a gun. Both House bills face an uphill battle in the Republican-controlled Senate, and the White House has signaled it would veto the measures.
