Senator Mike Duffy set Ottawa abuzz Monday with his latest revelations from the Senate floor. Duffy says Conservative party lawyer Arthur Hamilton was part of a scheme to cover his $13,560 legal bill. An audible gasp went up from senators as Duffy dropped his latest bombshell.

Duffy says he received two cheques as part of a larger plan he says was devised by the Prime Minister's Office. The legal bill payment is in addition to the original $90,000 cheque from Nigel Wright, the former chief of staff to Prime Minister Stephen Harper.

In his speech, Duffy maintained 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.

The embattled senator's claims sent many to Twitter to share their reaction to Duffy's account of his deal with the PMO.
