Sen. Mike Duffy is dispensing more bombshell revelations in the Senate, this time about a second payment related to his ongoing expense scandal.
Duffy says Conservative party lawyer Arthur Hamilton was involved in a scheme to cover his $13,560 legal bill.
The second payment is in addition to the original $90,000 cheque from Nigel Wright, former chief of staff to Prime Minister Stephen Harper, that touched off the whole controversy over Duffy's expenses.
An audible gasp went up from senators in the upper chamber as Duffy dropped his latest bombshell.
Duffy says the payments were part of an elaborate plan orchestrated by the Prime Minister's Office to make the controversy over his expenses go away.
He says he was well within the rules in filing his expenses, and that the true amount of claims that were in violation of the rules totalled less than $500.
