Homeland Security Secretary Janet Napolitano told Congress Tuesday that the Customs Bureau picked up Boston bomber Tamerlan Tsarnaev’s trip to Russia but not his reentry into the United States.

Napolitano’s testimony contradicted an FBI account related by Sen. Lindsay Graham (R., SC) who said Monday that the bureau had been unaware of Tsarnaev’s exit and reentry due to a clerical error.
