This is orthogonal to Tor. SSL protects an adversary from seeing what you're talking about, not who you're talking to. Tor will prevent an adversary from seeing who you're talking to, but not (in itself) what you're talking about[0]. Here, the topic of concern is an adversary (in this case, the government) finding out what you're talking about, so Tor isn't relevant.
