Legal experts say we’re not there yet; the White House dismisses such concerns as “fearmongering” The theory called the "unitary executive" has gained broad support in Republican circles and reached its peak under Trump , legal experts say.

The growing power of the presidency will be on display when Trump delivers a major address to Congress on Tuesday .

A federal judge in California temporarily blocked Trump 's large-scale termination of probationary employees by finding the Office of Personnel Management didn’t have the authority to fire “probationary employees that you have not identified as mission-critical” The likelihood of Trump defying the Supreme Court is "nil," a constitutional law professor says.

Trump 's priorities will be hurt more if the policies become viewed as unpopular than from any decisions by lawmakers or judges, legal experts say.

Trump 's approval rating after the first month since his return to office is nearly 48% a shade higher than his disapproval rating according to an average of polling by FiveThirtyEight.com.
