Still, Trump is expected to be acquitted of both charges in the Senate, where Republicans have the majority, in what will be only the third presidential impeachment trial in U.S. history. Proceedings are expected to begin in January.
Trump lauded House Republicans for remaining in lockstep against impeachment as a few Democrats crossed the aisle to oppose it.
"We have to say it was a bipartisan vote," Trump said. "No Republican went to their side."
Speaking to thousands of enthusiastic supporters, many wearing his campaign paraphernalia, Trump encouraged young conservatives to stand up to the "radical left," as he sought to harness the nation's cultural and divisions for political gain.
"Each of you are on the front lines of defending our way of life," Trump said. "The radical left doesn't stand a chance against young conservatives who put America first."
Trump spoke on the first day of his more than two-week winter vacation at his private club in Palm Beach. Trump was introduced by conservative talk radio host Rush Limbaugh, who encouraged the high school students in attendance not to believe in climate change and for conservatives to attack Trump's critics, not spend time defending him.
"The people that need to be defending themselves are the people attacking him and the people attacking us," Limbaugh said. "The president doesn't need to be defended. He needs to be supported."
