Speier discussed her decision today on ABC7 Mornings, saying it wasn't easy to make. She loves serving her constituents, but it was time to spend more time with her family.

The 71-year old says she still has more to contribute, but she's not sure yet on what she plans to do when her career on Capitol Hill comes to an end in January of 2023.
"I'm still going to be involved in our communities, I still want to be giving back. I would love to see a foundation created for San Mateo County because there really isn't one, and its a very wealthy county, but its also subject to a lot of pain and suffering by many of our constituents, so I don't know, but I'm open to all the possibilities," Speier said.
"Such an iconic figure. When you think about San Mateo County you have to think about congresswoman Jackie Speier. You think about what she's done around consumer protection and around women's rights. She is truly beloved by her constituents," said San Mateo County Supervisor David Canepa.
Congresswoman Speier said what she is most proud of during her time in Sacramento was changing child support enforcement laws.
"Also the baby bullet train San Francisco to San Jose cutting commute time in half. And here in Congress, it's been a labor of love around sexual assault in the military and on college campuses," said Speier.

"She gave a voice to survivors so that people could really understand the pain and the retaliation they were facing while serving our country. Jackie is one in a million. She's a 'she-ro' to many of us," said Nancy Parrish with Protect Our Defenders.
Speier has served California's 14th District of San Mateo County and the Peninsula since 2013 as well as the 12th District of San Francisco back in 2008 to 2013. But her career really starts far before then.
Exactly 43 years ago this week, Speier survived being shot five times as part of the 1978 Jonestown massacre in the country of Guyana. She was serving as an aide to Congressman Leo Ryan, who was assassinated -- one of 909 people who died at the settlement. They were on a fact-finding mission to investigate claims of human rights abuses by Jim Jones and followers of his San Francisco-based cult.
