Ralph Nader, the activist and former Green Party presidential candidate, condemned President Donald Trump's team Thursday, saying that many of his appointees are violating their oaths of office and failing to enforce laws in the best interests of the American people.

He made the comments on MSNBC's "The Beat" with host Ari Melber. He was particularly critical of Environment Protection Agency Administrator Scott Pruitt, who has been under fire for a series of scandals that continue to emerge and that many believe may soon force his ouster. But he was also critical of other administration officials, such as Director of the Office of Management and Budget Mick Mulvaney.

“I’ve never seen anything like it,” Nade said. "This is the deepest form of corruption and shutting down of law enforcement agencies.”

He added that the members of Trump's Cabinet who violate their oaths of office are "serial impeachment candidates," though the Republican Senate is unlikely to act to stop them.

"They are flouting congressionally passed laws, violating them, by subverting them, shutting down enforcement, harassing civil servant investigators, and raising money from the very crooks they're supposed to be prosecuting and putting in jail," Nader continued. "These are high-level, government-installed crooks. And I say that clinically. They're violating their oaths of office to enforce the laws of the land."
