Katie Zacharia hits ground running, promises Trump diesel deal delivers cheaper gas for Americans

"President Trump has heard people have been frustrated with the gas prices. People are frustrated with the increasing grocery prices. And he is delivering what he always does, which are solutions," Zacharia said Saturday.

"President Donald Trump has never been unambiguous. He is an America-first president. He is putting [American interests] first, American citizens first with this deal. And we will have cheaper gas, cheaper groceries with this diesel deal," she added.

"He did it with Venezuela, and he did it with-he's doing it with Canada and did it in Greenland. So, I think we're [going to] see some historic wins, and President Trump is [going to] deliver that," she said.

The incoming press secretary then shifted her focus to November's midterm elections. She argued the president has "delivered historic results," but said congressional Republicans could have accomplished more by passing key legislation, including the SAVE America Act.

"I would have loved to see more from our congressional Republicans in the Senate. I think President Trump has done everything in his power to do that," Zacharia said.

"This is what happened with Joe Biden, basement Joe, for the 2020 election. We didn't see him until we had to," Zacharia told Watters.

"They think they can hide these candidates and we won't notice," she added.

"Becerra's disappeared, Talarico disappeared. And it's on purpose because they know they can't continue letting them talk because they're destroying their campaigns," Zacharia said.

Zacharia also revealed how she learned of her White House appointment, telling Watters that Trump personally called her with the news.

"I got a wonderful phone call from the chief talent recruiter, the president himself," she said. "He loved what a fighter I was for him... I just get to continue doing what I've been doing, which is promote all of the things that President Trump is doing on behalf of the American people."

"She has an unblemished record of support, and has been a loyal and brilliant supporter, right from the beginning. She is, likewise, a devoted fan and member of MAGA! I am confident that Katie will deliver strong results for our Country as the next White House Press Secretary, as she has the respect of, and will work fantastically with, the Media, the American People, and my Administration," he added.
