Senate Majority Leader Harry Reid (D-Nev.) warned colleagues that the Senate might have to eat into its summer recess to deal with pressing issues.

Reid said Tuesday that he'd warned senators to not plan much vacationing during the first week in August, when Congress typically breaks for a monthlong district work period.

The top Senate Democrat's admonition comes as the Senate is working to finish its current legislative priority, Wall Street reform, as quickly as possible before a recess around Memorial Day.

This Congress has seen shifting deadlines in the Senate, especially on healthcare,  throughout the past year and a half, and lawmakers have worked long nights and weekends, especially close to holidays. The Senate, for instance, voted on Christmas Eve morning to pass its preliminary health reform bill. 

Reid's words may also serve as a jolt to those who have maybe hoped for a less aggressive legislative agenda in the coming months, ahead of what's expected to be a tough midterm election in November for Democrats. Reid has his own tough reelection challenge to fight off, and the August recess is prime time for campaigning.

"I said 'one week' in August," Reid responded when asked if senators could stay in Washington any longer than that.

Still on the agenda following financial reform are some emergency spending measures, as well as, in the longer-term, an energy and climate bill, and a possible comprehensive immigration reform effort.
