Leftist hack organization masquerading as a union.

(CNN) – As the U.S. Senate prepares for its first procedural votes on the “Gang of Eight” immigration plan, a top labor union is launching a seven-figure ad buy on cable television.

The Service Employees International Union (SEIU) said Tuesday that five different spots that feature police officers, small business owners, veterans, children of undocumented immigrants and Republicans will run through June, encouraging Congress to pass comprehensive immigration reform, including ads

Labor unions and business leaders were initially at odds over immigration reform, but reached an agreement on guest workers earlier this year that allowed the Gang of Eight plan to move forward.

The SEIU, which represents 2.1 million workers in a wide swath of American service industries, has long endorsed Democrats in political races, and backed President Barack Obama in 2008 and 2012.
