For this round of talks, the bipartisan group has added Sen. Lamar Alexander (R-Tenn.), a former member of Minority Leader Mitch McConnell’s (R-Ky.) leadership team, and Sen. Michael Bennet (D-Colo.), who has grown close to Obama as he tries to capture Colorado this election season.

Senate insiders confirmed the upcoming session, although the group will not disclose its location.

“This group continues to meet and work toward a bipartisan solution,” Warner spokesman Kevin Hall said.

Other Gang of Six members include Sens. Dick Durbin (D-Ill.), Kent Conrad (D-N.D.), Saxby Chambliss (R-Ga.), Mike Crapo (R-Idaho) and Tom Coburn (R-Okla.).
