Former President Barack Obama released a statement Friday endorsing Senator Dianne Feinstein (D-Ca.), 84, for reelection to the Senate, amid speculation that she might have trouble facing off other Democratic candidates come November.

Why it matters: Obama has begun to reinsert himself back into the political sphere after months of staying away from Washington affairs. In March, Politico first reported that he will appear at a fundraiser for Senator Claire McCaskill (D-Mo.) in Beverly Hills on May 6.
