HARRISBURG, Pa. (AP) — Robert F. Kennedy Jr. won’t testify in defense of his effort to appear on Pennsylvania’s presidential ballot. That’s after he showed up late Tuesday to a court hearing in Pennsylvania where Democratic activists are trying to bar him from the ballot in the battleground state. Kennedy’s lawyer blamed a canceled flight from Boston to Philadelphia. Lawyers for the challengers say Kennedy’s candidacy paperwork states a fake home address and falls short of the signature-gathering requirement applied by state law to third-party candidates. Kennedy’s campaign dismisses the challenge as “frivolous.” Should Kennedy appear on Pennsylvania’s ballot, he could siphon support from Republican nominee Donald Trump or Democratic nominee Kamala Harris.
