President Obama and former President Clinton will address Senate Democrats during their annual retreat next week, according to a Democratic aide.
Obama usually addresses the retreat, and Sen. Charles Schumer (D-N.Y.) invited Clinton to appear this year.
The Democratic lawmakers will gather at the Washington Nationals baseball team's stadium, just more than a mile south of the Capitol complex.
Landrieu and Hagan raised eyebrows when they declined to attend events with Obama in their home states in recent months, suggesting the president might be viewed as a liability by the lawmakers.
On Tuesday, Senate Majority Leader Harry Reid (D-Nev.) said he would encourage vulnerable Democrats to still campaign with the president.

And people love this man. They love his family," Reid told CNN. "Of course, with what the Republicans have been doing, trying to denigrate him with what's happened with the rollout of ObamaCare, but things, even this week, his numbers are going up again."
On Thursday, White House press secretary Jay Carney dismissed concerns about Democrats' unwillingness to appear with the president.
"He obviously supports Democratic candidates, both incumbents and challengers across the country, and I think we’ve amply demonstrated that support already and he will continue to do so," Carney said.
