Mayor Gavin Newsom says his newborn daughter is home safe.

The mayor rushed to the California Pacific Medical Center early this afternoon to pick up his baby, who was born Friday, following an online campaign event involving Twitter.

Just before 3 p.m., the mayor apologized via Twitter for slowing traffic.

“I think we drove 3 mph,” he wrote. “Sorry for traffic jam!”

Newsom and his wife recently moved into a home in Ashbury Heights.

The mayor’s wife, actress Jennifer Siebel Newsom, was scheduled to come home today as well, the mayor said Monday.
