I’d say it was a rogue staffer.
If that is the case, maybe Cruz should be more careful who he gives access to his twitter account to.
It’s not like he gives his account to somebody. Politicians are old and don’t have time for Twitter. They let their staff handle it. I don’t think Ted Cruz had control over the hiring of this hypothetical staffer.
I am not talking about the hiring of the staffer, I am talking about giving the staffer access to his twitter account. A politician should be very careful when giving his/her username and password to things like twitter accounts.
