Sen. Dianne Feinstein away from Washington due to "health matter"

Sen. Dianne Feinstein is away from Washington, D.C., this week as she deals with a "health matter," a spokesperson for the retiring senator from California said. 

Feinstein announced last month that she won't be seeking reelection next year, but at 89, she still has nearly two years left in her current term. 

"The senator is in California this week dealing with a health matter," a spokesperson for Feinstein said. "She hopes to return to Washington soon."
