Jessica Alba posed for photos in a skirt by Jane Oh at a press conference in Washington DC this morning. She spoke to reporters about the Safe Chemicals Act with New Jersey Senator Frank Lautenberg after arriving on the East Coast late last night. Jessica got involved in the campaign earlier this month, since the Safe Chemicals cause is important to pregnant women tying to create a healthy environment for their families. Jessica took a break from activism, though, to spend time with her little one on Saturday at the park with pals Eric Dane and Rebecca Gayheart. Honor stayed home when Jessica attended a friend's wedding that night with her husband, Cash Warren, but the threesome were back together for breakfast at The Griddle in LA on Sunday morning.
