OTTAWA - Conservatives on a Commons committee want to cast a wide net to catch other Liberals they suspect are involved in a Twitter attack against Public Safety Minister Vic Toews.

One fish of interest is MP Justin Trudeau, but the ethics committee hopes to get former Liberal research bureau staffer Adam Carroll to rat on others.

Asked whether that includes anyone from the leader's office, others at the bureau and at party headquarters, Conservative MP Dean Del Mastro said: "You bet."

Another Conservative said Trudeau has some explaining to do for retweeting some of Carroll's rants at the height of the Twitter volleys.

"I also think it's important that we know how the member for Papineau (Trudeau) was involved in this campaign," Conservative MP Candice Hoeppner said in the Commons during debate on Bill C-30 - the Internet snooping bill that triggered the Twitter blasts.

NDP MP Pat Martin said inviting Carroll to committee is nothing more than a diversionary tactic.

"The oldest - the oldest trick in the book is to say, 'What a stupid place to hang a piano and then everybody looks, wow,'" Martin said. "It's change the channel at all costs."

The NDP will counter the majority Conservative motion with one of their own calling for Michael Sona - the former Conservative staffer linked to the so-called robocall election fraud allegations- and officials from the Racknine calling centre to appear as well.

Carroll was the employee interim Liberal leader Bob Rae said was behind a Twitter account that exposed the sordid details of Toews' divorce and other matters.

While Carroll broke no laws, Rae gave up the staffer after House of Commons IT sleuths zeroed in on government computers used by the Grits as the source of the Twitter tirade.

Rae said Carroll acted alone and accused Prime Minister Stephen Harper of a double standard.

"They seem to be prepared to investigate all kinds of things except their own behaviour."

The motions will be presented at committee Thursday.
