President Donald Trump's sweeping assertions of executive power during his first weeks back in office appear headed toward U.S. Supreme Court showdowns, but it remains an open question whether or how much the justices might act to check his authority.

President Donald Trump’s administration is switching positions in a major Supreme Court case on transgender rights, backing away from the Biden administration’s opposition to Tennessee’s ban on gender-affirming care for minors.

The Supreme Court majority built by Donald Trump could uphold efforts to expand presidential authority based on the legal principle of unitary executive theory.

The Supreme Court also refused to pause briefing in a consolidated case involving appeals of two lower court decisions, Oklahoma v. EPA and PacifiCorp v. EPA. Both cases center on EPA’s denial of 21 state implementation plans for slashing ozone pollution that crossed state lines.

President Donald Trump has faced several setbacks from federal courts, which have blocked or paused some of his most controversial plans since taking office.

While it was once rare for an administration to change its position in cases before the high court, Trump did so in his first term and has signaled he will do it again.

A federal judge on Thursday paused the Trump administration's "buyout" offer for federal employees hours before it was set to expire. Multiple judges have now ordered freezes on President Trump's plan to end birthright citizenship.

A federal judge who already questioned the constitutionality of President Donald Trump’s birthright citizenship executive order is set to hear arguments over a longer-term pause of the directive.

Now the question is whether the court rulings are a mere speed bump or an insurmountable roadblock for the Republican president.
