US President Joe Biden has publicly sought out Jackie Walorski, an Indiana Congresswoman who died in a car accident in August, seeming to forget that she had passed away.
Attending a conference, Mr Biden thanked other conference organisers then asked: "Jackie are you here? Where's Jackie?"
Ms Walorski, a Republican, was one of four Congressional co-sponsors of the bill to fund the conference. She and two members of staff died in early August.
Mr Biden moved past the issue without any correction. After Ms Walorski's death, the White House issued a statement from Mr Biden that said he and his wife Jill were "shocked and saddened" by her sudden accident.
"Truly an awful and disgraceful blunder," Representative Vicky Hartzler, a Missouri Republican, tweeted in reference to the mistake.
White House Press Secretary Karine Jean-Pierre said the president's confusion stemmed from having Ms Walorski on his mind as he presided over the conference and also thought ahead to hosting her family at the White House this Friday.
"She was top of mind," Ms Jean-Pierre said.
"He was thinking about her as he was naming, he was calling out the congressional champions on this issue, on this really critical issue," she said.
"I feel like many of us have gone through that particular, you know, time, where someone is on top of mind and you call them out."
