She made herself a pubic figure by testifying before Congress.....
She didn’t formally testify before congress. The house republicans refused to let her testify because she had no expertise or knowledge that had bearing on the hearing (constituionality of obamacare). The democrats set up a mock hearing situation made to look like it was a real hearing.
That she testified before congress is a lie (now she’s a lying slut).
She allowed herself to be put on national public display in a publically aired forum so she is a public figure.
