As Twitchy reported earlier Wednesday, Marco Rubio was making some noise about running for the Senate again, and why not? Even though he had said he wouldn’t return to the Senate after his failed bid for the presidency, polling has him ahead of the two Democrats running for his seat.

Those polls might change again very soon as the results of an investigation into Rep. Patrick Murphy by CBS4 News make the rounds on social media.

It is a long piece, but this tidbit from CBS Miami sums up the investigation pretty well:

So when Murphy said in 2012, “I got my CPA license and I spent years going to numerous Fortune 500 companies,” the truth is he only spent at most eight months – and not years – with Deloitte & Touche holding a CPA license valid only in Colorado, a state where Murphy has never lived or worked.

A campaign spokesman acknowledged Murphy did not meet Florida’s educational requirements to become a CPA, nevertheless he sought a license in Colorado because “Patrick was excited to start his career.”

The campaign then added: “As a fully-licensed CPA, Patrick is a member of the Florida Institute of Certified Public Accountants.”

Is it too late for Joe Biden to establish residency and jump in the race?

Murphy hasn’t responded to the CBS Miami investigation on his Twitter feed, but he does have a pretty high-level endorsement pinned to the top.
