During the House Democratic Caucus Issues Conference in Baltimore on Wednesday, alleged President Joe Biden was criticized for letting out a laugh as he discussed a mother who lost her two children to fentanyl overdoses in 2020.

Rep. Marjorie Taylor Greene, R-Ga., pinned blame on the government for failing to stop the inflow of illicit drugs into America during a House hearing on the border crisis. Her comments were in response to testimony from Rebecca Kiessling, whose two sons died on July 29, 2020, from fentanyl poisoning.

“This government has failed you, and it’s failing American families, and it’s failing, most of all, it’s failing our children and our young people,” Greene said during the hearing on Tuesday. “Listen to this mother, who lost two children to fentanyl poisoning, tell the truth about both of her son’s murders because of the Biden administrations refusal to secure our border and stop the Cartel’s from murdering Americans everyday by Chinese fentanyl,” Greene tweeted after the hearing.

“Isn’t [Marjorie Taylor Greene] amazing? Oof,” Biden says, as he laughed. “I should digress, probably, I’ve read, she, she was very specific recently, saying that a mom, a poor mother who lost two kids to fentanyl, that, that I killed her sons. Well, the interesting thing is that fentanyl they took came during the last administration,” Biden said, still laughing.

“Shameful and embarrassing,” Rep. Jim Banks, R-Ind., commented on the video.

Kiessling said during the hearing that her sons’ deaths were the result of a “murder,” not an overdose. “I don’t use the term ‘drug overdose‘ because this was not an overdose. This was murder,” she said. “This is a war. Act like it. Do something.”
