Donald Trump has said "I have the right to do whatever I want as President" under Article II of the Constitution and that "it gives me all of these rights at a level that nobody has ever seen before ... but we don't even get there ... we haven't had to use it yet."
Now Trump is asserting his determination to "get there," and if he comes to power in 2025 the "yet" part of his assertion will have arrived.
The Trump campaign's "Project 2025" reveals Trump's plans for mass deportations and detention of American citizens against whom he wants to exact "retribution" - such as "radicals" and the American media which he calls "the enemy of the people." Trump's plans to use emergency powers (particularly the Insurrection Act, which would entail the use of the United States military against American citizens) has been detailed by Trump's advisers in Project 2025 and then reaffirmed by Trump himself in speeches and media posts.
Trump's declaration that a president has the "right" to do "anything I want" is what Safeguard and The Petition to Safeguard the Constitution have been created to specifically counter, and the dangers of this assertion are illustrated in "The War After the Election."
