According to the latest filing with the Federal Election Commission, Congresswoman Elizabeth Esty has returned about $350,000 in donations to individuals and PACs, but still has more than a million dollars in the account.  Esty opted not to run for reelection amid a controversy over her handling of a sexual assault complaint involving her former Chief of Staff.  Contributions earmarked for the November election must be returned while money left from previous campaigns or undesignated doesn't have to be.  The money can be used to wind down campaign operations or donated to other candidates, but can't be spent on personal use.
