It was about one month ago.
If it seems like it has been much longer, that's because a lot has happened since then. He's greenlighted the Dakota Access and Keystone XL pipelines. He's enacted his promised Muslim ban and vowed to take the courts, er, to court when a panel of judges upheld an earlier stay against the ban. He's restored the "global gag rule" on abortion, killed the Trans-Pacific Partnership and pushed the Affordable Care Act to the brink.
And that's only a smattering of his actions during his first month as the leader of the free world, not even accounting for the controversial Cabinet he's assembled and his many bizarre Twitter feuds.
So what can we glean from this first month of Trump about what we're in store for from here on out?
Trump was serious on the campaign trail
All that talk about building walls and banning Muslims? Yeah, he wasn't just playing to the base to get elected. Though the U.S. will pay for his "great wall" until Mexico pays us back (yeah, right), Trump has moved quickly on many of the most incendiary of his campaign promises, including his xenophobic immigration ban.
Trump is going to keep being Trump
During the campaign, and especially after, many wondered if Trump would ever mature and become "more presidential."
One month into his presidency, it is clear that Trump is going to be the same guy he was on the campaign trail, the same guy he was on his reality show and the same guy he was as a businessman. He's going to keep tweeting, he's going to keep stretching the boundaries of the truth and he's going to keep bashing the media. He's not going to turn into Abe Lincoln anytime soon — Trump will always be Trump, and he will always have his enablers and apologists.
But he will face opposition
His administration has proven clumsy in many regards. The Muslim ban had a chaotic roll-out and is currently being blocked by the courts; Republicans still don't have a plan to replace the ACA; and his national security adviser has already resigned over compromising conversations he'd had with the Russian ambassador to the United States. In-fighting appears to be rampant inside the White House, and Trump reportedly is struggling to adapt to the enormity of his role.
