Former President Donald Trump said on Monday that Vice President Kamala Harris was attempting to con the American public by shifting her positions on border security and copying his proposal to remove taxes on tips.

Harris made headlines over the weekend after she said she would eliminate taxes on tips if elected president at a rally in Las Vegas, a policy first proposed by Trump two months ago.

“Kamala Harris has flip-flopped on virtually every policy she has supported and lived by for her entire career, from the Border to Tips, and the Fake News Media isn’t reporting it,” Trump posted on Truth Social on Monday. “She sounds more like Trump than Trump, copying almost everything. She is conning the American public, and will flip right back. I will MAKE AMERICA GREAT AGAIN! There will be no flipping!!!”

Trump first proposed stopping taxing tips in June, also at a rally in Las Vegas.

“So this is the first time I’ve said this, and for those hotel workers and people that get tips, you’re going to be very happy because when I get to office, we are going to not charge taxes on tips, on people making tips,” Trump said at the rally. “And I think it’s going to be something that is deserved — more importantly — popular or unpopular, I do some unpopular things too, if it’s right for the country, I do what’s right.”

Trump also ripped into Harris’s recent narrative that she is tough on border security. One of her new ads claims that she supported “the toughest border control bill in decades” and refers to her as a “border state prosecutor.”

“Kamala Harris was put in sole charge of the Border,” Trump said on Monday. “It quickly became the WORST AND MOST DANGEROUS BORDER IN HISTORY. As President, Harris will completely DESTROY OUR COUNTRY!”

Republicans have pushed back, pointing to the record number of illegal immigrants who have entered the country during the Biden-Harris administration and her reported role as Biden’s “border czar.”

Trump currently maintains a narrow lead in five of the seven key battleground polls, according to the most recent average of polling. Harris has narrow leads in both Wisconsin and Michigan.
