Adam Carroll says he acted alone when he set up the @vikileaks30 account to embarrass Toews over an Internet snooping crime bill privacy advocates and civil libertarians say goes too far.
The Commons ethics committee served notice Tuesday that Carroll will be called to answer lingering questions about whether others key Liberals in the party's research bureau, leader's office or party headquarters were aware of the source of the Twitter attacks before the account was closed.
Carroll did not break any laws by tweeting public details of Toews' personal life.
Interim Liberal leader Bob Rae named Carroll as the culprit on Monday after apologizing to Toews in the House of Commons. The Conservatives had accused the NDP of being behind the Twitter account and did some mea culpas of their own in the House.
An investigation by House of Commons IT security experts pinpointed the @vikileaks30 account to the Grits on the weekend.
