Looks like Angelina Jolie isn’t the only member of her family getting involved in humanitarian pursuits.

[IMGCAP(1)]Jolie’s older brother, James Haven, is scheduled to join “Veronica Mars— actress Kristen Bell and other celebs at the How It Ends lobby days this week, urging Members of Congress to pass legislation calling on the U.S. to disarm a Ugandan guerrilla group, the Lord’s Resistance Army.

The two-day event kicks off at the Walter E. Washington Convention Center today, where Sen. Russ Feingold (D-Wis.) and Rep. Jim McGovern (D-Mass.) will join policy experts at a symposium designed to educate participants on the efforts to apprehend LRA leader Joseph Kony.

On Tuesday, the activists will come to Capitol Hill, where they’ll spend the morning at a rally in Upper Senate Park before visiting Congressional offices in the afternoon. Participants will ask Members to sign onto legislation introduced by Feingold, McGovern and others urging the U.S. to “apprehend or otherwise remove Joseph Kony and his top commanders from the battlefield.—

Kony has been indicted by the International Criminal Court for crimes against humanity but remains at large. A variety of activist groups have urged the U.S. to lead the effort to capture him.

A closing rally featuring musical performances by artists such as Nada Surf will be held at the Ellipse between the National Mall and the White House on Tuesday night.

And although Haven will be involved in heavy policy matters over the next few days, HOH notes that his weekend was far less serious: He attended the Radio and Television Correspondents’ Association Dinner on Friday night as a guest of Fox News.
