It depends on the language in the trust.
If the trust can be amended anytime by the settlor-
she can change it again to make herself or someone of her choice
The answer given does not imply that an attorney-client relationship has been established and your best course of action is to have legal representation in this matter.
If the trust is revocable (or amendable), your aunt can either amend the trust or if she prefers she can revoke it. In California, a trust is revocable and amendable unless specifically declared to be irrevocable. Your aunt should go see an estate planning lawyer about regaining control of her assets.

I agree with the answer of Attorney Symons. If revocable, your aunt can remove the current trustee and designate herself as the new trustee or revoke the trust and require all trust property be transferred to her.
Before doing anything, though, she needs to go over the trust with an attorney experienced in trusts and trust administration to determine her options are available. She can find a lawyer through Avvo's "Find a Lawyer." Alternatively, she may want to contact the Los Angeles County Bar's referral program.
