Both sides of the Internet gambling debate are doubling down in Washington. (See what we did there?)

A 1961 law called the Wire Act was reinterpreted by the Justice Department in 2011 to allow for Internet gambling, which was previously illegal. A bipartisan group of lawmakers has teamed up to restore the Wire Act to its original interpretation – that is, to ban Internet gambling.

Two special interest groups have hired lobbyists to fight for and against Internet gambling.

In other words: It is on.
