My mom recently visited me here in the U.S. on a tourist visa last month. She's visited the U.S. many times (during all of Obama, Trump-1st and Biden), and her experience this time was no different than the previous times if not "a little bit simpler" in her own words. The only thing different was that she finally met a CBP officer that speaks Mandarin, and she was asked about whether she has brought excessive amount of cigarettes or meat/fruit... That's it.
I'm a U.S. citizen now, but I haven't traveled during Trump's 2nd term yet. During his first term, however, I went to Canada once, and at Vancouver Airport, you go through U.S. passport control before boarding the plane. That time, I was asked how I became a U.S. citizen, and I told him via marriage. Then he let me go. I didn't know why he asked the question though, because he should have access to that info if he wish to obtain, so maybe he was just curious as he was Asian too? I've traveled outside of the U.S. both as a LPR and a citizen more than a handful of times, and that was the only time I was asked an immigration-related question.
Oh, I went back to China right before the Pandemic in January 2020, which was during Trump's first term. By the time I was coming back, only U.S. citizens and LPRs were allowed in. My flight was switched 3 times understandably, and passengers from China had to go through a quick health screening, but again, re-entering the U.S. was no issue.
