The Senate Ethics Committee has decided not to investigate Louisiana Senator David Vitter.
The Republican was linked to an elite Washington prostitution ring owned by Deborah Jean Palfrey. Palfrey committed suicide May 1st, two weeks after being convicted of racketeering and money laundering.
The bipartisan ethics panel says it decided against a probe because the conduct occurred before Vitter became a senator. And it says it didn't result in any criminal charges or involve the improper use of his public office or status.
