The White House on Tuesday abruptly canceled a planned energy summit between President Barack Obama and a bipartisan group of Senate lawmakers, citing a scheduling conflict.

Obama had been scheduled to meet with Majority Leader Harry Reid (D-Nev.), Minority Leader Mitch McConnell (R-Ky.), their respective leadership teams, and the chairmen and ranking members of relevant committees Wednesday morning. According to Senate aides, the meeting was planned to discuss the chances of comprehensive energy legislation.

According to a schedule for Obama, it appears that the energy summit was pre-empted for a meeting with Gen. Stanley McChrystal, who has come under fire for comments he made about Obama and administration officials in an article that will appear in Rolling Stone magazine.

A White House aide said Obama hopes to reschedule the meeting for early next week.
