The caretaker accused in a lawsuit of isolating Robert Indiana before his death is suing the pop artist's estate for $2 million to cover his legal fees.
Jamie Thomas worked for Indiana for years and serves on the Star of Hope foundation, which aims to transform Indiana's island home into a museum to display his work.
But Thomas and another man are accused in a federal lawsuit filed in New York of making unauthorized reproductions of Indiana's work.
Thomas filed his lawsuit Friday.
