A few notable quotes from the article follow:

“A Super Pac affiliated with Robert F Kennedy Jr, the anti-vaccine conspiracy theorist running for president as a Democrat, owes half its cash to a longtime Republican mega-donor and Trump backer, according to campaign finance reports filed on Monday.”

… and further…

“Kennedy’s campaign attracted a considerable amount of support from Republican donors in the weeks since he announced his run in April. A political watchdog found that Kennedy has a “long history” of antisemitism, racism and xenophobia.”
