Tracking Trump's visits to his properties and other conflicts of interest

Kentucky Governor Matt Bevin's campaign benefited from flood of money from the RGA, which under a loophole in the tax code, doesn't have to disclose its contributors until next year—keeping voters in the dark.

The FEC announced it would take no legal action against one of the most notorious dark money groups involved in the 2010 elections, despite overwhelming evidence.

Outside spending by non-disclosing groups has reached new heights in this election cycle—an unfortunate trend showing that federal agencies need to institute and enforce stricter controls.

CREW filed a complaint last week with the IRS against a nonprofit that is a supposed "social welfare organization"—and therefore doesn't have to disclose its donors—but clearly exists almost entirely to support Sen. Marco Rubio's presidential campaign.
