The New York Times and CNN reported this week that Kennedy, whose approval rating was 8.7 percent in a nationwide Hill poll, will support Republican nominee Donald Trump after he withdraws.
In the tight race for the presidency between Democrat Kamala Harris and Trump, Kennedy supporters' votes could decide the outcome in some states, analysts say.
Kennedy is an environmental lawyer and longtime vaccine skeptic whose campaign has struggled to attract mainstream voters.
His campaign said last night he would address the nation from Arizona, where Trump is scheduled to hold a campaign event that day.
“Independent presidential candidate Robert F. Kennedy Jr. will address the nation live on Friday about this historic moment and his path forward,” the campaign said in a brief statement.
The New York Times yesterday quoted three unnamed sources as saying Kennedy would end his campaign and potentially endorse Trump.
CNN quoted two unnamed sources as saying that Kennedy is expected to suspend his campaign on Friday.
