DENVER (AP) — Two people who were booted from a Denver public appearance by then-President George W. Bush have lost their bid to revive their lawsuit against the people who asked them to leave.

Leslie Weise and Alex Young claim their First Amendment rights were violated when they were ejected from the Wings Over the Rockies Air and Space Museum in 2005. Bush was appearing at a taxpayer-funded town hall to tout his plan to privatize Social Security. In a 2-1 decision Wednesday, the 10th U.S. Circuit Court of Appeals said volunteers Jay Bob Klinkerman and Michael Casper cannot be sued because they were acting in their official capacity.

Weise and Young claim they were singled out because they had a bumper sticker that read, "No More Blood For Oil," a reference to the Iraq war.
