Sens. Ben Sasse and Deb Fischer are among 15 Republican senators who are urging Senate Majority Leader Mitch McConnell to consider cancelling the traditional August recess to work on unfinished business.
"We have long-term problems that the Congress isn't serious about fixing," Sasse said in a statement.
"And, this is a simple fact: Our issues won't go away while the Senate is spending August elsewhere.
"The budget will still be broken. We still won't have serious strategies for the age of cyber and jihad. Putin's thugs will keep working to divide us. And we'll still be on the brink of a trade war."
The Senate should stay in session and work overtime, Sasse said.
"We can't keep burying our heads in the sand as if everything will be magically better tomorrow, especially as our adversaries around the world look to get a foot up on us. We have too much work to do."
