In Washington, D.C., a Senate committee on organized crime is investigating the Corleone family. Pentangeli agrees to testify against Michael, who he believes had double-crossed him, and is placed under witness protection. On returning to Nevada, Fredo tells Michael that he felt resentful for being disregarded. He claims to be ignorant of the plot on Michael's life and informs Michael that the Senate lawyer is on Roth's payroll. Michael disowns Fredo but orders a capo to continue protecting him while their mother is alive. Michael sends for Pentangeli's brother from Sicily, resulting in Pentangeli renouncing his previous statement; the hearing dissolves in an uproar. Kay reveals to Michael that she actually had an abortion, not a miscarriage and that she intends to remove their children from Michael's criminal life. Outraged, Michael strikes Kay, banishes her from the family, and takes custody of the children.
