"Livid"

Joe Kennedy was reportedly “livid” about the Twitter altercation, The Boston Globe reports. The tweet about the Kennedy family's mental health came the same month Joe Kennedy was a pallbearer at his 22-year-old cousin Saoirse Kennedy Hill's funeral.

An aide to Kennedy confirmed to The Boston Globe that Senator Markey called Kennedy to apologize.

Senator Markey said in a statement to The Boston Globe: “To show such insensitivity for those experiencing mental health issues is extremely offensive to me.”

“This action by a member of my campaign is unacceptable. It in no way reflects my commitment to the issue of mental health treatment and the eradication of stigma that so many families suffer. I deeply apologize to Congressman Kennedy and his entire family.”
