From CBC PEI:

Shortly after his court vindication, Senator Mike Duffy returned to charging taxpayers for some of his Ottawa living expenses.

According to the Senate's quarterly proactive disclosure report, Duffy claimed $1,691.59 in National Capital Region expenses between March and June of 2016.

These are the types of claims that led to the Senate expenses scandal in the first place, and prompted an overhaul of the rules and regulations for the Upper Chamber.

"I filed my claims as the Senate rules provide, and was approved by Senate administration, and as Judge Vaillancourt agreed were valid," Duffy told CBC News in an email.

Before the scandal broke in 2013, it had been widely known that Duffy, who represents Prince Edward Island, had lived in Ottawa for more than two decades during his time as a television broadcaster.
