Commerce Department general counsel Cameron Kerry - brother of Secretary of State John Kerry - has been named acting secretary of Commerce when the outgoing acting secretary, Rebecca Blank, leaves at the end of this month.

This may be the first time ever that two brothers served in the Cabinet at the same time. Of course, President John Kennedy had brother Robert as attorney general, but that’s not quite the same. (And won’t happen again because that move sparked a 1967 law, dubbed the “Bobby Kennedy law,” banning relatives of the president from getting such jobs.)
