Ahead of Trump speech to Congress, flashback to 2017 address asking 'What will America look like' at 250

"In nine years, the United States will celebrate the 250th anniversary of our founding - 250 years since the day we declared our independence," said Trump,who was elected to his first term in November 2016. "It will be one of the great milestones in the history of the world. But what will America look like as we reach our 250th year? What kind of country will we leave for our children?"

"These are kind of common themes when he speaks today, and those are gone," Tevi Troy, presidential historian and former HHS secretary under the George W. Bush administration, told Fox News Digital in an interview. "Those are not there. But that aside, there are a lot of similarities, and at first I was reading and wondering if it could be given in this administration, because there's a lot of the same stuff."

"He talks about borders in there, for example, and he talks about unleashing the American economy," Troy said. "And so the themes are the same, but some of the circumstances have changed."

"I could see that coming as an improv moment, but it's probably not in the speech's written," he said.

In addition, inflation is going to be on peoples' minds come Tuesday night.

Trump's 2017 address did not include inflation, but he does mention restarting "the engine of the American economy - making it easier for companies to do business in the United States, and much, much harder for companies to leave our country."
