Robert F. Kennedy Jr., scion of the Kennedy political family, who in recent months has been vying for the Democratic presidential nomination, is expected to announce an independent candidacy for the U.S. Presidency on Monday.

He is the nephew of assassinated President John Fitzgerald Kennedy and son of (also assassinated) presidential candidate Robert Kennedy.

In a statement, the Kennedy campaign said the 69-year-old politician would make a “much-anticipated announcement” in a speech Monday afternoon (Tuesday morning in Greece) in Philadelphia.

In the speech, he “will share his vision for a profound realignment of American politics and the healing of the nation’s widening partisan divide,” the statement added.

Polls put Kennedy, who is running for the Democratic nomination against Joe Biden, at 15 percent nationally. However, polls show he is more popular among Republicans than among Democratic supporters.

Kennedy has a history of opposing vaccines, while he also has expressed views in the past deemed controversial like his concerns that wifi causes “brain leakage” and chemicals in water cause gender dysphoria.
