"Dianne Feinstein's Daughter's Power of Attorney: A Battle for Control"

Democratic Senator Dianne Feinstein's daughter, Katherine Feinstein, has a power-of-attorney agreement that grants her some say over the senator's affairs. Katherine, a former San Francisco judge, filed a lawsuit on her mother's behalf last month, seeking to become the sole trustee of her mother's late husband's trust. The extent of Katherine's power over the 90-year-old lawmaker is unclear. The issue has raised questions about Senator Feinstein's ability to fully serve in Congress, as she has faced health concerns and episodes of confusion.
