Sen. Dianne Feinstein (D-Calif.) has filed a lawsuit against the trustees of a trust established by her late husband, alleging financial elder abuse. The suit was filed by Feinstein's daughter, Katherine Feinstein, who was given a limited durable power of attorney in July. The lawsuit seeks to remove the trustees and to receive the millions of dollars Feinstein is due from the trust. Feinstein, who is 90 years old, has taken a series of legal actions in recent years to protect her financial interests. The lawsuit is ongoing and it is unclear when a resolution may be reached.
