President-elect Donald Trump pledged to make a huge splash on his first day back in office from the beginning of his campaign to recapture the White House.

Trump stated that he would utilize executive orders on "Day 1" to circumvent the regular legislative process and obtain significant changes to U.S. policy with a single stroke of his pen. He made this claim in a number of early videos detailing his ideas as well as in campaign speeches across the nation.

By signing an executive order alerting federal agencies that, "under the correct interpretation of the law," children of undocumented immigrants do not automatically obtain citizenship by virtue of their birth on U.S. soil, he pledged to unilaterally overturn the long-standing constitutional guarantee of birthright citizenship.

"I will reverse the disastrous effects of Biden's inflation," he declared.

Conservative members of Congress have stated that the president-elect plans to act swiftly and forcefully — with their support — and media outlets have reported that over 100 executive orders are in the works. Trump's promises have long thrilled Republicans and alarmed Democrats, but the excitement has grown ahead of his inauguration on Monday.

"A lot is conceivable, but not on 'Day 1,'" said Bert Rockman, a professor of political science at Purdue University who is an expert on executive and presidential authority. "Beyond [Trump's] statements, it is probably impossible to expect that many things would be done immediately."

Another is the matter of legal challenges. California and other leftist states filed challenges throughout his first term, often preventing Trump from using executive orders to carry out his agenda. California Attorney General Rob Bonta says those states are already getting ready to fight Trump's agenda again.
