It actually is true you can tell a person by the company he keeps. In Florida today, Newt Gingrich got a nice warm introduction from none other than Rep. David Rivera (R-Fla.). Has Gingrich slipped completely off his rocker?

Rivera is the poster boy for GOP scandals. Politico reported in March:

Florida Rep. David Rivera, under an ethical cloud and facing an expanding investigation into his finances, is in a political squeeze from Republicans in Washington and Miami just two months into his congressional tenure.

Republicans are already privately floating the names of potential primary challengers to Rivera, and on Capitol Hill he’s found himself increasingly isolated as leaders try to distance themselves from his troubles back home.

In late September the Hill reported: “Multiple criminal investigations have slammed the brakes on Rep. David Rivera’s (R-Fla.) fundraising efforts as members of the House Republican leadership have distanced themselves from the embattled freshman. The FBI, IRS, Miami-Dade police public corruption unit, Miami-Dade State Attorney’s Office and Florida Department of Law Enforcement are all investigating Rivera over allegations that he abused his former seat in Florida’s state House of Representatives for personal financial gain, and repeatedly lied on financial disclosure forms.”

That’s Gingrich’s warm-up act. The two do in fact have a connection. Judicial Watch, a right-leaning watchdog group, put both Gingrich and Rivera on its list of most corrupt politicians for 2011. Really, you can’t make this stuff up.
