I mean, I suppose he could drugged Ford and transported her across state lines. But, I don't think that has been alleged yet.
So, I don't think they can just order an investigation. I'm pretty sure that the Dems don't want to give the "Hey, go investigate this random person" power to Trump. But, who knows.
Having said all that, I'm not a criminal lawyer, and its been a while since I took Crim Law. And, there are so many federal laws, and I'm sure they can get Ford to say something that implicates one of them. If she says, "He asked me to go to the beach," that might be enough if they had to cross a state line...you know, human trafficking.
