The Kennedy family will come out in force to endorse Joe Biden at a campaign event in Philadelphia today, since Biden is likely more at risk from Robert F. Kennedy Jr.'s third-party challenge than Trump is. Via Axios:

RFK Jr.'s sister, Kerry Kennedy, will invoke the legacy of her slain father, former Attorney General Robert F. Kennedy, as well as that of her uncles: former President John F. Kennedy and Sen. Ted Kennedy (D-Mass.).

"I can only imagine how Donald Trump's outrageous lies and behavior would have horrified my father," she will say, according to prepared remarks shared with Axios.
"President Biden has been a champion for all the rights and freedoms that my father and uncles stood for," she will say, joined by more than a dozen members of the Kennedy clan.

Biden will be introduced by Joe Kennedy III, a former member of Congress who currently serves as the president's special envoy to Northern Ireland.

After Biden's remarks, Kennedy family members will knock on doors and make calls on behalf of the Biden campaign.
