Less than an hour after the ABC News presidential debate ended Tuesday night, Vice President Kamala Harris‘ campaign called for another matchup, laying down a challenge to former president Donald Trump.

The campaign put out an email touting her performance at the debate and blasting Trump for his responses and demeanor.

The email ended with a direct question to the former president.

“Under the bright lights, the American people got to see the choice they will face this fall at the ballot box: between moving forward with Kamala Harris, or going backwards with Trump. That’s what they saw tonight and what they should see at a second debate in October. Vice President Harris is ready for a second debate. Is Donald Trump?”

Trump responded personally — in an unusual visit to the “spin room” with reporters afterward.

“They want another debate because they lost,” he said. “So, we’ll, you know, think about that.”

A second presidential debate has not been announced.

The vice presidential candidates are scheduled to debate on Oct. 1.
