I don’t think it is. But if you do something illegal with the account, it is crime. I won’t even use a fake account. I want nothing to do with them.
Funny thing is, even if President Trump did everything the democrats have accused him of doing, I'm not sure he actually did anything illegal.
I'm pretty sure that it's illegal to sell U.S. foreign policy in exchange for "donations" to your family's charitable foundation but the only people talking about this were the "fake news" accounts on Facebook.
Bottom line, Mueller's got nothing and that's why President Trump allows this charade to continue.
