The nation's largest federation of labor unions has released an ad calling Donald Trump no friend of the working man, possibly to counter his appeal among white, blue-collar voters.
An ad from the AFL-CIO shows Trump saying wages are too high, talking about his father giving him a million dollar loan, and bragging that he is "really rich."
Trump's rise to the top of the Republican presidential ticket has been fueled by overwhelming support among working-class, white voters.

Like labor unions, Trump has been critical of free trade agreements like the North American Free Trade Agreement and the Trans-Pacific Partnership.
In January, a study released by Working America , an affiliate of the AFL-CIO, showed that among voters in working-class neighborhoods outside the Rust Belt cities of Cleveland and Pittsburgh who had already decided on a candidate, a third of them supported Trump.
Most of the major labor unions have backed either Democrats Hillary Clinton or Sen. Bernie Sanders , while the AFL-CIO has held off on a formal endorsement so far.
