Bundy has garnered notable right-wing support for his refusal to recognize the government's authority over federal land. His latest comments, however, targeted African-Americans who depend on public housing and went so far as to suggest that black Americans were better off as slaves.
"I've often wondered, are they better off as slaves, picking cotton and having a family life and doing things, or are they better off under government subsidy?" Cliven said, the New York Times reports.
Last week, when discussing the armed standoff between the federal Bureau of Land Management and Bundy and his supporters, Senate Majority Leader Harry Reid, D-Nev., called Bundy and his armed allies "domestic terrorists."

Sen. Dean Heller, R-Nev., responded, "What Sen. Reid called 'domestic terrorists,' I called 'patriots,'" said Heller. He noted that he's supported efforts to transfer some federal land in Nevada to state control.
Heller's office told CBS News that the senator repudiates the rancher's most recent remarks.
"Senator Heller completely disagrees with Mr. Bundy's appalling and racist statements, and condemns them in the most strenuous way," a spokesperson for the senator said.
On Thursday, the senator responded on Twitter to Bundy's recent remarks: "Cliven Bundy's remarks on race are offensive and I wholeheartedly disagree with him," he said.
In an attempt to defend his remarks, Bundy held a news conference Thursday, telling reporters, "The question is are they slaves the way they are, or where they live to slaves to charity or government subsidized homes, and are they slaves when their daughters are having abortions and their sons are in the prisons?"
"I thought...would they be happier if they was home with their talking about the South? Where they come from?" he continued. "They came to Las Vegas for something better, but wouldn't they be happier at home? With their gardens and their chickens and their children playing around them, and their family having work to do? Would they, would they?"
Right-wing media have linked Bundy's feud with the government to plans the the Bureau of Land Management is drawing up for land in Texas. On "CBS This Morning" on Thursday, Gov. Rick Perry, R-Texas, said that Bundy's dispute with the government was a "side issue."
"The real issue here is the federal government and how the federal government deals with these issues of private citizens," he said.
Asked about Bundy's racist remarks, Perry said, "I don't know what he said, but the fact is Cliven Bundy is a side issue here compared to what we're looking at in the state of Texas. He is an individual - deal with his issues as you may. What we have in the state of Texas... is the federal government is coming in and attempting, from our perspective, to take over private property. And you must -- if this country's to stay the land of freedom and liberty, private property rights must be respected."
