President Donald Trump is back in the White House and moving at breakneck speed.

In his inaugural address, the new president vowed that conditions across the country would "start changing today, and they will change very fast."

Shortly after, White House deputy chief of staff Tyler Budovich teased on social media: "Now for the shock and awe."

They're not kidding.

Trump unplugs: The new president is doing something Biden rarely does

Trump signed a raft of executive orders and actions in his first eight hours in office, fulfilling a major campaign promise but also allowing the returning president to flex his executive powers and address some long-standing grievances .

The president immediately launched a crackdown on immigration, launched a trade war with top allies and rivals, and reversed many of the policies implemented by former President Joe Biden, including repealing much of the previous administration's federal diversity action and energy and climate provisions.

He also stirred significant controversy by pardoning or commuting the sentences of approximately 1,500 supporters who participated in the Jan. 6, 2021, attack on the U.S. Capitol in a failed attempt to overturn Congress's certification of Biden's 2020 election victory. Those who received commutations include some who violently attacked police officers during one of America's darkest days.

Trump also fired a number of senior administration officials, made a high-profile $5 trillion tech investment announcement, held an unscripted, wide-ranging, informal and impromptu press conference in his first two days back at the White House, and even The bay was renamed the Gulf of America, Mexico.

"I think they've done a great job handling this, taking immediate action to meet this moment. That's exactly what he needs to do and what the people voted for," senior Republican strategist Kristin Davidson told Fox News .

"Americans voted for decisive, fast action and real leadership. Trump understands this better than anyone. I think he and his team know how important it is to show they hear the wishes of the people and respond with leadership Important," Davidson argued.

Longtime Republican consultant Alex Castellanos agrees

Castellanos, a veteran of multiple Republican presidential campaigns, told Fox News: "He's pouring into the area. He's making the case for action. He's demonstrating action. He's rallying the American people to protest against the government. Support for scale transformation.”

Veteran Democratic strategist Joe Caiazzo didn’t dispute Trump’s frantic actions.

"This speed should not be surprising to anyone," Caiazzo said. "Trump has made it very clear that he will act quickly, he will act boldly, and he will do exactly what he told voters Do." .

But he argued that "what he has done will have a direct negative impact on working families across the country. It also demonstrates his lack of respect for the rule of law."

Trump's avalanche of executive orders

Asked if Trump's actions were what Americans voted for last fall, Caiazzo responded: "Of course not. What Americans voted for was cheaper groceries. Donald Trump will give We brought a litany of policies that would worsen our institutions, policies that would undermine our institutions “to enrich the rich and entrench his position in this country’s oligarchy. "

There’s another reason Trump is moving so fast — even though he’s new, he’s also a term-limited lame-duck president. By Labor Day, much of the political world will be looking ahead to the 2026 midterm elections.

"This is his second term. He has to act quickly," Davidson stressed.

Trump's performance in the early days of his second administration also stands in sharp contrast to when he first entered the White House eight years ago.

The president and his team were much more experienced the second time around, and supporters were fiercely loyal to Trump.

"In past administrations, there would be gridlock and bottlenecks because someone disagreed with him," a senior White House source told Fox News. "Now we have a whole infrastructure and staff built around him to support him. When When he says something, it gets done. That's a testament to him and the team he's built."

White House chief of staff Susie Wiles also deserves credit for keeping the train on track as co-campaign manager of Trump's 2024 presidential campaign.

"What Susie did was look at Trump's whole package, find the best players, and put them in the best position to support the president. Trump surrounded himself with Trump's people, and they've proven that over the years Not only is he loyal, but he is a super capable operator," added the consultant, who requested anonymity to speak more freely.
