Actually the hat says " Make America Healthy Again" - my previous translation was in error - it's been a while since I studied Russian.

"Free" would have been свободно and "great" would have been Великий.

It's been a while since I studied it as well (if you can call my efforts 'studying'—my grades didn't reflect much studying). I used Google Translate and when I did, I too got Великий. So I then entered "здорово" which is the third word on the hat and Google came up with "great". Don't know who he consulted when he had his hat made up—his being so clever and all.
