President Donald Trump was inaugurated to begin his second term on Monday and he wasted little time before he began to undo some of the accomplishments of his predecessor, former President Joe Biden.

Just hours after being sworn in, Trump signed several critical executive orders at the inaugural parade in Washington D.C.'s Capitol One Arena in front of a loudly cheering packed house, Spectrum News reported.

That was just a taste of what was to come, however, as the new president ultimately signed off on more than two dozen various executive actions and orders before his first day was finished.

Undoing what Biden did

President Trump's first executive order was arguably the most significant in that it took a figurative axe to former President Biden's achievements.

Titled "Initial Recissions of Harmful Executive Orders and Actions," that order effectively revoked 78 executive actions, orders, and presidential memos issued by Biden over the past four years that covered a vast range of topics.

Trump described the plethora of actions taken by Biden to have been "destructive and radical" but boasted that they were all now "null and void."

Next, Trump signed a "Regulatory Freeze" to halt any new or pending regulations until they could be reviewed by his people, not holdover career bureaucrats, which he followed up with a "Hiring Freeze" for new federal civilian workers, after which he signed a "Return to In-Person Work" order that, as the name implies, ordered all federal employees to cease working from home and return to their federal office spaces.

Those federal employees may not be back in their offices for very long, though, as the new president insisted that "most of those bureaucrats are being fired" in the near future.

Withdrawal from the Paris Climate Agreement

Another major executive order that President Trump signed at the inaugural parade in front of thousands of cheering supporters was one that once again withdrew the U.S. from the 2015 Paris Climate Agreement, which he has long argued placed unfair environmentalist constraints on the U.S. economy that aren't equally applied to competitor nations.

Titled "Putting America First in International Environmental Agreements," the order authorized a U.S. withdrawal from not just the Paris Climate Agreement but also ended commitments to related ventures like the United Nations Framework Convention on Climate Change and the U.S. International Climate Finance Plan.

Spectrum noted that this is now the second time that Trump has withdrawn the U.S. from the Paris Agreement that was first entered into by former President Barack Obama in 2015, was exited by Trump in 2017, and then re-entered by former President Biden in 2021.

Weaponization of government and censorship of free speech

President Trump signed two more substantial executive orders at the inaugural parade that likely had deep personal meaning for him given his experiences during the four years that separated his two terms in office.

The first of those was titled "Ending the Weaponization of the Federal Government," which is intended to halt the use of federal agencies to go after political opposition with civil actions, investigations, and prosecutions.

The last of Trump's orders was called "Restoring Freedom of Speech and Ending Federal Censorship," which will prohibit federal employees from using the powers of the government to censor and silence the free speech rights of U.S. citizens.
