Donald Trump and Kamala Harris are set to square off on primetime tonight.

The candidates’ first presidential debate in the sprint to Election Day will air live on ABC starting at 9 p.m. ET. Those without cable can tune into the debate through any live TV streamer with access to ABC, such as Sling TV, Fubo and Hulu + Live TV.

Sling TV, which currently offers a 3-day free trial, is the best way to watch the Harris-Trump debate live online.

The debate, which will air live from Philadelphia, has been scheduled since August after the former president said he would like to do three debates in September. Only tonight’s ABC debate has been confirmed by all parties.

“I hear that Donald Trump has finally committed to debating me on September 10,” Harris said on X following the announcement. “I look forward to it.”

Trump originally agreed to debate President Biden on ABC on Sept. 10, but withdrew that commitment after Biden dropped out of the race. The Harris campaign charged that Trump was “too scared” to debate, and said that Harris would show up whether he was there or not.

The stakes are high for both the former president and current vice president as their respective campaigns spring into high gear in the leadup to November. With Election Day only eight weeks away, there’s a good chance this will be their only debate of the campaign — and their last chance to win over critical battleground states on a major stage.

ABC’s David Muir and Linsey Davis will moderate Tuesday’s night debate, where they’ll introduce the candidates and seek to “enforce timing agreements and ensure a civilized discussion,” per ABC’s debate rules.
