Before Andy Puzder adopted Trump's hard line on immigration, his chains' restaurants had to cut loose more than 1,000 undocumented workers.
While Andy Puzder ran Hardee's, its franchisees altered timecards, deducted pay for uniforms and even broke child labor law.

The workers were paid with prepaid debit cards, which came with fees that pushed their pay below $7.25 per hour, according to Labor Department records.
