Vice President Joe Biden and special envoy to the Middle East peace process Martin Indyk will speak at the annual conference of J Street, a group that promotes the two-state solution based in Washington.

"I think it underscores that the [American] administration is taking leadership to resolve this crisis a real priority," Jessica Rosenblum, director of media relations at J Street, told The Jerusalem Post. "For us, Secretary of State Kerry set forth a mandate for us to rally a great constituency for peace, and that's what we intend to do at this conference."

The vice president is the highest-level guest to speak to the conference since it began four years ago.
