The Office of the First Lady has notified the Secret Service after actor Peter Fonda called for kidnapping Melania and Donald Trump’s son, Barron, The Daily Caller has learned exclusively.

In a tweet sent Wednesday, the actor called for Barron to be “ripped” from Melania’s arms and put in a cage “with pedophiles.”

“WE SHOULD RIP BARRON TRUMP FROM HIS MOTHER’S ARMS AND PUT HIM IN A CAGE WITH PEDOPHILES AND SEE IF MOTHER WILL WILL STAND UP AGAINST THE GIANT ASSHOLE SHE IS MARRIED TO,” Fonda tweeted early Wednesday morning.

Spokesperson for the first lady Stephanie Grisham told The Daily Caller that the Secret Service has been “notified” of the threat.

“The tweet is sick and irresponsible and USSS has been notified,” Grisham said. (RELATED: Here Are The Photos Of Obama’s Illegal Immigrant Detention Facilities The Media Won’t Show You)

Fonda has been on a twitter tirade against White House officials, particularly females and children, over the past few days.

He called for the public caging and rape of Department of Homeland Security Secretary Kristjen Nielsen in a tweet Tuesday. In the vulgar tweet, Fonda said “Kristjen Nielsen is a lying gash that should be put in a cage and poked at by passersby.” He continued, “The gash should be pilloried in Lafayette Square naked and whipped by passersby while being filmed for posterity.”

Fonda also proposed that Press Secretary Sarah Sanders three children get kidnapped and locked in a basement while calling her a sexist slur. “SS (Sarah Sanders) is a lying gash, too,” Fonda said, “And “gash” is much worse than cunt. Maybe we should take her children away and deport her to Arkansas, and giving her children to Stephen Goebbels Miller for safe keeping.”

DHS and the office of Sarah Sanders has yet to respond to request for comment.

Sony Pictures is releasing a movie starring Fonda in a matter of days called ‘Boundaries.’
