RFK Jr. says Kamala Harris was lying to Americans about Biden's condition: 'Concealer in chief'

Robert F. Kennedy Jr. is encouraging Democrats to have an "open process" to pick their presidential nominee after President Biden announced that he is not seeking re-election.

"The Democrats really need to do what President Obama said, which is to have an open process, a genuinely open process. So much of the primary process was rigged," Kennedy said on "Fox & Friends" Monday.

However, the independent presidential candidate believes there is no evidence of the Democratic Party planning to do so.

"It has to be some kind of fair process because it looks to the American public that the system is just rigged, which it is," said Kennedy, who was blocked by the party from challenging the president in the primaries.

Kennedy, who previously ran as a Democrat before switching to independent, said he will not seek the party's nomination.

"I'm not going to get into the Democratic Party as long as the system seems rigged. If they had a fair system, I would. I would definitely look at it."

Kennedy added, "if they [Democrats] looked at the polling, I'm the only candidate who can beat Donald Trump."

With VP Kamala Harris now in the running with Biden's backing, Kennedy said she has some "explaining to do" about why she helped hide the true nature of the president's condition.

"She was seeing the president every day, and she was telling the American public again and again, 'he is completely capable of running the country. There's no signs of a deterioration. There's no signs of cognitive impairment.' And that clearly was not true."

He added, "Whoever she runs against, she has a big vulnerability … because she's been the concealer in chief."
