Robert Kennedy apologises after video of him speaking to Trump leaks online

Robert F Kennedy Jr apologised Tuesday after a video was posted online showing part of a private phone call between the independent presidential candidate and Republican former President Donald Trump.

The video shows Kennedy listening on a speakerphone as Trump shares disproven claims about childhood vaccines, an issue that has helped Kennedy amass a loyal following among people who reject the scientific consensus that the benefits of vaccines far outweigh the risk of rare complications. Trump also appears to pitch Kennedy on endorsing his campaign.
