OK, now I see it.
But it's NOT part of the official statement.
It's her twitter lead in to her official statement.
You'd think that if she actually believed that that she would make it part of her official statement.
What you're seeing is posturing, and aside comment, but she's not actually extending it to her official statement because she knows, as an attorney, that Biden is full of *expletive deleted*it.
She wants to look like she's supporting him and the cause but not be stupid enough to make an official statement that could bring her future credibility as an attorney into question.
I see it as her being very conniving.
