The Office of Congressional Ethics recently released its second-quarter report for 2014 , and in the middle is a pie graph that gives congressional nerds some insight into what ethical lapses the OCE has been looking into since its inception.  

The chart tracks preliminary investigations conducted by the independent ethics office, and, as the graph illustrates, the plurality of investigations since February 2009 — 46 percent — have involved campaign activities.  

The OCE reports it has conducted 137 preliminary investigations since 2009, with 49 of those cases transmitted to the Ethics Committee for review.  

In addition to the pie chart, the OCE’s quarterly report also reveals that the Ethics Committee is supposed to name two members under investigation on Friday, though no details of the investigation are expected to be released and the Ethics Committee will likely vote to take an additional 45 days to consider the matter.  

The OCE also revealed in the quarterly report it voted to refer an entity to the U.S. Attorney’s Office for failing to register under the Lobbyist Disclosure Act.
