Something to keep in mind as President Obama heads into the trilateral summit with Pakistan's Asif Ali Zardari and Afghanistan's Hamid Karzai this week: There is a Congressional Pakistan Caucus.

The caucus is co-chaired by Reps. Dan Burton (R-Ind.) and Sheila Jackson Lee (D-Texas). There are 70 members in the caucus.

Pakistani American Leadership Center says the mission of the caucus is twofold: "(1) To facilitate dialogue between Pakistani Americans with their political representatives in Congress and (2) To improve and strengthen bilateral relations between Pakistan and the U.S."

Zardari is scheduled to meet with the caucus, as well as the House Foreign Affairs Committee, on Tuesday.
