In democratic systems, the courts are a vital check on a leader’s power. They have the ability to overturn laws and, in Donald Trump’s case, the executive orders he has relied on to achieve his goals.

Since taking office, Trump has targeted the judiciary with a vengeance. He has attacked what he has called "radical left judges" and is accused of ignoring or evading court orders.

The Supreme Court has already handed the Trump administration some key wins in his second term. But several cases now before the court will be pivotal in determining how much power Trump is able to accrue – and what he'll be able to do with it.
