“We are committed to striving every day to meet the standard set by the President in treating others with dignity and respect, with civility and with a value for others through our words and our actions,” Ms Psaki’s statement said.
As the story broke on Friday, Ms Psaki said Mr Ducklo apologised to the reporter “with whom he had a heated conversation about his personal life”.
Mr Ducklo, who was national press secretary for Mr Biden’s 2020 election campaign, issued a statement on Twitter addressing his “intolerable actions.”
“No words can express my regret, my embarrassment, and my disgust for my behaviour. I used language that no woman should ever have to hear from anyone, especially in a situation where she was just trying to do her job,” he said.
“It was language that was abhorrent, disrespectful and unacceptable.”
Mr Ducklo added that he was “devastated to have embarrassed and disappointed my White House colleagues and President Biden.”
Politico Playbook, the Washington politics tips and gossip newsletter that Ms Palmeri reports for, wrote this week that Ms McCammond made it public in November that she was dating Mr Ducklo.
A day after being sworn in as president, Mr Biden warned his White House staff against mistreating others.
“I’m not joking when I say this: if you are ever working with me and I hear you treat another colleague with disrespect, talk down to someone, I will fire you on the spot.”
