Before a crowd of liberal activists at a Washington, D.C., hotel, AFL-CIO President Richard Trumka will train his sights Tuesday on conservative Democratic Members, who he claims are siding with Republicans in thwarting the majority’s agenda.

“It is a fact of American public life today that the Congressional Republicans are the ‘party of no.’ They have decided that they will profit from failure,” Trumka will say, according to an advanced copy of his speech provided to Roll Call. “They are short-selling America. They are not just watching our collective house burn and hoping to pick up the ruins on the cheap.

“They are cutting the fire hoses and sometimes even pouring on the gasoline. And unfortunately they have some help,” the speech continues. “Because, up on Capitol Hill, there is a handful of Democrats who are afraid to do what’s right for America.”

Trumka is expected to deliver his speech at 1:15 p.m. Tuesday at the Campaign for America’s Future “America’s Future Now!” convention, which runs through Wednesday at the Omni Shoreham Hotel. His remarks also come as union-backed Arkansas Lt. Gov. Bill Halter battles Sen. Blanche Lincoln in Tuesday’s Democratic primary runoff, a contest that has hinged on Lincoln’s anti-labor voting record.
