ROCK HILL, S.C. (AP) — President Donald Trump on Thursday canceled weekend rallies in Iowa and Kansas, opting instead to support Republican candidates with telerallies that his party said could reach more voters in nearly two dozen states in the final days of a midterm election.

Trump was scheduled to hold a rally in Kansas on Saturday and in Iowa on Sunday. But the Republican National Committee announced Thursday evening that he would instead spend a “72-hour sprint” doing rallies by phone rather than in person, a move the RNC said would maximize his ability to speak to voters nationwide. The RNC said telerallies are planned for nearly 20 states, and more may be announced.

The decision to switch to telerallies means Trump will be expected to speak for about 10 minutes instead of more than 90, as he does at in-person events.

Asked whether the change was tied to an illness, Trump denied being sick and said he’s not traveling to Kansas “because he’s doing very well,” an apparent reference to Marshall.

“I don’t feel I have to go to Kansas,” Trump said, adding that he still plans to travel to Florida on Friday.
