Former President Donald Trump is open to Robert F. Kennedy Jr.'s participation in presidential debates, while President Biden's campaign insists on limiting debates to Biden and Trump.

Trump suggests Kennedy must meet CNN and ABC News' criteria to join debates, taunting Biden by calling Kennedy 'sharper and more intelligent'.

Robert F. Kennedy Jr., facing exclusion, is striving to meet debate criteria, including garnering 15% support in national polls and securing ballot access in enough states.

Despite Kennedy's efforts, he currently exceeds the 15% support threshold in only two national polls and is on the ballot in six states, with legal challenges expected.

Trump and Biden agree to two debates, on June 27 and September 10, rejecting participation in a further three debates offered by other hosts.

Kennedy accuses Trump and Biden of collusion to prevent his debate inclusion, while Trump labels Kennedy a 'Democrat plant' amidst signs of Kennedy drawing support from both candidates.
