President Trump is continuing to move ahead with deportations and sweeping changes to the federal government. His administration is running into some obstacles in the courts but that hasn't stopped him from seeing just how far he can go.

Meantime, Trump's also dealing with a series of foreign-policy hotspots, while taking aim domestically at opponents.

Here are five takeaways from the week:

1. Running into the courts: Trump is testing the limits of the presidency, doing as much as possible without Congress. To this point, that's meant tackling a lot — like restructuring the federal government, laying off workers, dismantling agencies and taking over boards of once semi-independent outfits. But while Republicans, who control both houses of Congress, are eager to give Trump the reins, there is another equal branch — the judiciary.

This week saw the courts become speed bumps once again in what Trump is trying to do, from his immigration deportations, his ban on transgender military service members or his attempted termination of climate-related grants through the Environmental Protection Agency. The Trump administration is pushing back, and the president himself called for the impeachment of a judge in one of the cases. That didn't sit well with Chief Justice John Roberts, who said "impeachment is not an appropriate response to disagreements concerning a judicial decision."

An NPR/PBS News/Marist poll from earlier this month found that 58% weren't confident Trump would follow court orders if they block his executive actions. And he will undoubtedly test just how far the courts will let him go with cases that presumably end up at the U.S. Supreme Court.

2. What to fight for: Democrats are not unified on how to oppose Trump (as evidenced by Senate Democratic leader Chuck Schumer's unwillingness to let the government shut down last week.) The courts are the avenue many on the left see as the best way to thwart Trump's agenda. But the right believes they have public opinion on their side on many of the issues landing in court.

As they see it: Why would Democrats be against deporting people the administration says are gang members; someone who, they say, was promoting Hamas' position on a college campus; or a doctor who allegedly had photos of a Hezbollah leader on her phone? Those on the left would argue it's not about what people are accused of, it's about adhering to court orders, regardless of what someone is accused of, an idea that's as old as the republic and John Adams defending British soldiers.
