DES MOINES, Iowa (AP) — A year after the children of radio personality Casey Kasem had to seek court action to see their ailing father, a new Iowa law aims to ensure that adult children can see their sick parents — granting them visitation rights unless the person’s guardian goes to court to stop them.

Gov. Terry Branstad signed the bill Friday. The law gives an adult with a legal guardian — someone who cannot manage their own affairs — the right to receive visits from family members and others they have previously expressed interest in seeing.

Sen. Rob Hogg said he started working on the issue after hearing from a constituent having difficulty visiting her brother. The legislation was backed by Kasem’s daughter, Kerri Kasem, who appeared on Iowa radio to advocate for it.
