Congress returns from a two-week spring recess Monday, April 8, 2013, with gun control and immigration high on the Senate's agenda. Senators could start debating Democratic-written gun legislation before week's end, but leaders may decide to give negotiators more time to seek a deal on expanding background checks for firearms buyers.
