President-elect Donald Trump, in the latest stop of his victory lap, told a military veteran-laden crowd in Florida that while he would build up the country's armed forces, he would use them sparingly as commander-in-chief.

"For too long, we've moving from one reckless intervention to another, to countries you've never heard of before," Trump said at a rally Friday night in Orlando. "It's crazy and it's going to stop."

Trump still vowed to defeat the Islamic State group, offering no details but promising a foreign policy strategy that "means crushing ISIS rapidly."

Trump on Friday also selected South Carolina Rep. Mick Mulvaney, a budget hawk and conservative Republican, to be his budget director, according to a transition official not authorized to speak publicly about the decision before it was announced.

The stop in Orlando was meant to salute Trump's Election Day victory in a must-win state for his upstart presidential bid. The Republican businessman, who owns multiple properties in Florida, calls it his "second home" and relentlessly campaigned across it, successfully turning out white voters from non-coastal areas to best opponent Hillary Clinton's strength among minority voters in the state's large cities.

He was in vintage campaign form Friday, settling scores, belittling opponents and even conducting a poll from the stage as to whether the crowd liked the phrase "Made in America" or "Made in the USA" better. ("Made in the USA" won convincingly.)

The raucous crowd — which was double in size of the one in the same venue in late October — also acted as if the campaign was still ongoing, repeatedly chanting "Lock her up" about Trump's former Democratic foe Hillary Clinton. They also turned their scorn on the press pen, chanting "Move them back" when Trump bitterly noted that the reporters at the rally had better seats than most of the attendees.

Trump's pick to head the Office of Management and Budget helped found the House Freedom Caucus, the group of conservative lawmakers who frequently battled former House Speaker John Boehner. An early backer of Trump during the campaign, Mulvaney took a hard line on federal spending under the Obama administration.
