Former President Donald Trump speaks during a campaign rally at the Central Wisconsin Airport on Sept. 7 in Mosinee, Wisconsin.

The Trump campaign on Monday gave a preview of the attack strategies former President Donald Trump is likely to employ during tonight’s presidential debate on ABC.

The campaign argued that Vice President Kamala Harris “owns everything in this administration.”

In a phone call with reporters ahead of Tuesday’s debate, Trump campaign spokesman Jason Miller pointed to the U.S.-Mexico border and illegal immigration, Harris casting the tie-breaking votes in the Senate to pass stimulus bills and the withdrawal of troops from Afghanistan as issues the campaign believes Harris “owns.”

Miller also said he expects “there will be some surprises in the debate tomorrow.”

Miller pointed to Harris’s CNN interview in which she said her “values ​​haven’t changed,” even as her positions on some issues have, and argued that this response “really opens the door to talking about what those values ​​are, what Kamala Harris has stood for all these years, all the way back to the beginning.”

Miller claimed that Harris was in charge of the country, not President Joe Biden, and at one point referred to the Biden administration as the “Harris-Biden” administration, even though Harris is not the president.

Of Trump, Miller said the former president “will be himself. I think that’s an important thing to keep in mind.” He added that Harris “is being drilled into this debate by new advisers who worked for President Obama and who she doesn’t know.”

Miller said, “All these new people, these strangers trying to put thoughts into her head. These folders full of statistics and details. She has no idea what any of this is. No idea. And she’s trying to figure out what kind of person she wants to be, because her positions are changing, even though her values ​​have stayed the same.”

When asked how Trump is preparing, Miller said Trump has given both longer interviews and short interviews, held press conferences, given speeches and held rallies.

“President Trump is prepared for every possible style of questioning because that’s what he’s done throughout his campaign,” he said.
