RFK Jr. has proven to be one of Donald Trump's worst appointments, a remarkable distinction given how deeply incompetent this entire administration is. Kennedy is an anti-vaxxer and believes in the most deranged strains of conspiracy theories.

This man is not only unfit for office, he represents a profound danger to the American people.
