In response to the Orlando terrorist attack, Senate Democratic leaders say they plan to try to force votes on an array of gun control measures in the weeks ahead and have threatened to block critical spending measures if the GOP-led Senate prevents them from bringing up their legislation.

Senate Democrats on Tuesday pledged to try to force a vote as soon as this week on a measure authored by Sen. Dianne Feinstein, D-Calif., that would block those on the terror watch list or in some cases, under federal investigation for terrorism, from purchasing guns and explosives.
