President Barack Obama will host a dinner with bipartisan Congressional leaders Monday at the White House with the aim of strengthening relations with Capitol Hill.

Speaker John Boehner (R-Ohio), House Minority Leader Nancy Pelosi (D-Calif.), Senate Majority Leader Harry Reid (D-Nev.) and their respective leadership teams are expected to attend, but Senate Minority Leader Mitch McConnell (R-Ky.) will not because of a prior commitment, according to staff members. Other Senate GOP leaders will attend.

Obama has also invited dozens of committee chairmen and ranking members, and the lawmakers’ spouses will also be included.

First lady Michelle Obama, Vice President Joseph Biden, Jill Biden, Cabinet members and senior White House staff will be present at the dinner, which will be held at 8:15 p.m. in the East Room, according to the White House.

Congressional aides in both parties said Obama has hosted similar social functions in the past in an effort to improve relations with House and Senate lawmakers.
