Joe Biden isn't directly apologizing to several women who have told stories about how his behavior made them feel uneasy.

The Democratic former vice president said Friday in Washington, D.C.: "I'm sorry I didn't understand more. I'm not sorry for any of my intentions. I'm not sorry for anything that I've ever done."

Biden says he's "never been disrespectful intentionally to a man or a woman."

Biden gave a speech to an electrical workers union conference on Friday as he nears a decision on whether to run for president in 2020. It was his first time speaking publicly since the women started telling their stories about his behavior with them.

Biden this week released a video acknowledging his behavior made some people uneasy and said he'll be "more mindful about respecting personal space in the future." Biden also said, "I will be more mindful about respecting personal space in the future."

Aides say Biden is negotiating with key potential national political staff members and is planning a late April announcement.

These are Biden's first public remarks since former Nevada politician Lucy Flores wrote in New York Magazine on Friday that Biden approached her from behind and kissed the back of her head in 2014.

Since then, another woman has said Biden grabbed her face when he was thanking congressional staff at a 2009 event.

In response, President Trump tweeted out a parody video made by one of his supporters. It shows the former vice president popping up behind himself and touching and nuzzling him, along with the caption "WELCOME BACK JOE!"

Biden allies insist the eruption has done little to slow planning for a 2020 campaign. Barring the unforeseen, he is expected to announce his candidacy after Easter and embark on a trip to early voting caucus and primary states.
