Take 2: I do solemnly swear

Both chambers of Congress are notoriously finicky about the use of cameras and electronic equipment — stow those iPhones and Blackberrys please — in the inner sanctum.

So for the benefit of the fourth estate, both the Senate and House re-enact the swearing-in ceremony.

Blumenthal’s was held in the Old Senate Chamber shortly after Republican Marco Rubio of Florida, who Blumenthal exchanged pleasantries with on his way into the ceremony.

Blumenthal introduced his wife Cynthia and four children to Biden, including his son, Matthew, 24, a Marine lieutenant.
