Jake Paul says Tommy Fury has an easy way to get to the United States, but is moving like molasses to actually make it happen ... claiming TNT is using his travel issues as a reason to back out of their fight.
As we previously reported, Fury posted an Instagram video earlier this week explaining he was denied traveling to the U.S. for Wednesday's press conference for the Paul fight ... saying he had no idea why he wasn't able to make the trip.
TMZ Sports has learned it all stems from the Fury family's ties to MTK Global founder Daniel Kinahan, who's currently under investigation for his alleged involvement in a massive drug operation .
