The complaint does not say which Senators were targeted.
Prosecutors said DeRisi began leaving the voicemails on September 27, the day Kavanaugh appeared before the Senate Judiciary Committee and denied sexually assaulting California psychologist Christine Blasey Ford decades ago.
DeRisi is accused of leaving threatening voicemails, in which he threatened to murder and assault two senators due to their support for Kavanaugh.
In the first voicemail, Derisi did not identify himself but claimed to have a "present" for the senator, according to a criminal complaint. "Side of your f--ing skull, you scumbag motherf--er". He denied the allegation and other uncorroborated charges of sexual misconduct from his teenaged years that went public late in the confirmation process.
According to the Polk County Sheriff's Office, James Royal Patrick Jr. posted on social media that if Kavanaugh was not confirmed, "whoever I think is to blame, may God have mercy on their soul". The defense says 9 mm ammo was found in his home but that Derisi has given his guns to his son and they are no longer in his home. If f-ing Kavanaugh gets in, he's dead f-ing meat! 9 millimeter, side of the head, you f***ing old bastard, ' according to TMZ. Actually even if Kavanaugh doesn't get in he's dead f-ing meat.
On Oct. 6, the day of Kavanaugh's confirmation, DeRisi is alleged to have told another senator, "You better pray this guy don't get in". Calling again less than an hour and a half later, he allegedly said, "I'm gonna get you". The FBI was able to track him down because he used his debit card to buy the phone.
Ronald DeRisi, 74, was taken into custody early Friday, and is expected to be arraigned later in the day in Central Islip federal court before Magistrate Judge Gary R. Brown.
Derisi previously pleaded guilty to making other harassing calls in a case that involved at least 15 calls he placed to a victim's home and office, according to the complaint.
Derisi, then 67, who was said to have lived closest to the tower, was charged with two felony counts of tampering and criminal mischief, after having allegedly caused about $100,000 in damage by cutting the feeder cables.
