FBI officials intercepted two suspicious packages at two separate mail facilities in Delaware, CNN reported.

Both packages were reportedly addressed to former Vice President Joe Biden. The packages contained the same potential pipe bombs that were sent to eight other people and media organizations in the past few days, the majority of which were recovered throughout the day Wednesday, NBC News reported.

The Clintons and the Obamas had packages sent to their homes, and CNN’s New York City office evacuated when an explosive was found in their mailroom on Wednesday. Other packages have been sent to newspapers, Democratic politicians and donors in recent days, including one that was recovered inside actor Robert De Niro’s Manhattan apartment building on Thursday morning.
