Travel to the US

Help me ladyreddit. I am a married woman in my 30s and my husband has been asked to go to a wedding in Atlanta in October. We're in the UK. We're both very boring and politically middle of the road now but we were socialists and members of the socialist party about 15 years ago. I am terrified of him going to the US right now, can't stop picturing Alex Pretti and reading the accounts of other European people who have been shackled or chained or detained for tiny minor administrative errors which sometimes weren't even their errors. The friend whose wedding it is has pretty right wing politics and seems sure this is all just liberal/leftie propaganda and everything is absolutely fine. I am sure this isn't the case, but husband is currently in a 'It's too risky for you to go but maybe I should go for the sake of the friendship' space. I don't want to forbid him to go but I am terrified. What should I do?
