Last week, he showed up in front of a federal courthouse in New York on a mule -- a reference to Civil War-era promises of assistance for freed African-American slaves.
'I'm sorry my tractor may slow things down, but any delay in traffic is small potatoes compared to the years of delay black farmers have endured in our pursuit of justice,' he said.
