It is the traditional two-week Spring break, although they prefer the word “recess” over “vacation”.
This is because they will be meeting constituents and giving speeches back home.
But their primary job is legislating, and Congress departed Washington with plenty undone.
First, the “sequestration” spending cuts left hanging during the last congressional break are still in place, their impact mounting.
Congress also managed to pass a budget resolution keeping the government open, declaring a temporary cease-fire on budget fights.
That makes time for post-vacation work on gun safety and immigration.
Democrat Senate Majority Leader Harry Reid has promised an April vote on a gun-regulation bill that includes a provision on universal background checks.
Loosening immigration laws is an issue with a bit more consensus than guns, but senators left town before drafting legislation.
By the way, the House has been in session just 36 days so far this year, the Senate just 33.
