Kamala Harris's campaign branded Donald Trump "scared" Saturday after he proposed to change the presidential debate schedule ahead of a rally in Georgia where he will try to halt the vice president's surging momentum in her bid to become America's first woman president.
In an overnight post on his Truth Social app, Trump said he was willing to debate Harris on the conservative Fox News network on September 4, while declining to participate in a previously scheduled debate on ABC.
Trump pitched the idea before going to a rally in Atlanta, where he will gather supporters in the same arena where Harris addressed an excited crowd of some 10,000 just this Tuesday.
Trump said he had "agreed" to the debate plan with Fox. And he said it would take place in Pennsylvania -- a crucial swing state in the US presidential electoral system -- in front of a live audience.
The Harris campaign dismissed this as "games."
"Donald Trump is running scared and trying to back out of the debate he already agreed to and running straight to Fox News to bail him out," Harris's campaign communications director Michael Tyler said in a statement. "He needs to... show up to the debate he already committed to on Sept 10."
The proposal to confront Harris on a network that has long supported him was the latest Trump effort to recapture the initiative in a campaign that had been entirely focused on a rematch against 81-year-old Joe Biden, until he dramatically dropped his reelection bid on July 21.
Since then, Harris, 59, has reenergized the Democratic base almost overnight.
She has raked in donations, reassembled the team behind Barack Obama's two historic election victories, and neutralized the solid lead that 78-year-old Trump had built against Biden in opinion polls.
On Friday, she secured the official Democratic nomination, backed by near unanimous party support.
Harris is due imminently to announce her vice presidential pick, with the popular governor of key state Pennsylvania, Josh Shapiro, a frontrunner. On Tuesday, she is set to launch a countrywide tour with her yet-to-be-named running mate.
Rally in battleground state
Late Saturday, Trump will be joined by his own vice presidential pick, Senator J.D. Vance, at the rally in Georgia -- another battleground state that will help decide who wins the Electoral College majority on November 5.
Trump lost narrowly to Biden there in 2020 and the state was at the center of his unprecedented attempts to overturn the results of the election and refusal to accept defeat.
The size of Harris's rally on Tuesday was a warning sign to the Trump campaign, which has long touted its ability to draw thousands of passionate supporters, in contrast to Biden's usually meager crowds.
The situation is a remarkable turnaround in a campaign where Trump had been appearing to gather force while Biden -- hurt by a disastrous debate performance in June and mounting voter concerns over his mental acuity -- was steadily slipping.
Harris's rapid entry has left the Trump campaign scrambling -- and Trump now the oldest presidential nominee in US history.
Adding to the changed dynamics, Harris is vying to become the first woman president and the first of Black and Indian biracial heritage.
Trump drew gasps at a convention of Black journalists this week when he claimed that Harris, who has identified closely with her Black roots all her life, was only pretending.
"She was always of Indian heritage, and she was only promoting Indian heritage. I didn't know she was Black until a number of years ago, when she happened to turn Black, and now she wants to be known as Black," he said.
