It is an image that is hard to forget: Karlheinz Schreiber arriving at the House of Commons ethics committee hearings last month with binders full of his personal documents.

These were documents he believed would help the committee sort through his dealings with former prime minister Brian Mulroney.

Well, it turns out those documents — which ran into the thousands of pages — weren't nearly enough.

The committee chair has sent a letter to Schreiber's lawyer, Edward Greenspan, requesting even more documents by Jan. 15.

Committee members are looking for some specific things. Among them: Day-timers, personal notebooks and bank records. Anything that might help them muddle through the allegations Schreiber has made.

Schreiber's legal team is happy to cooperate, it seems. But it also wants to up the ante.

Greenspan doesn't feel his client is being treated the same way as the former prime minister and he wants to make sure that changes.

In his response to the committee, Greenspan says that he would like to know what documents Mulroney will be requested to table before the committee as well.

What's more, he has some suggestions what they should be. Things like the tax returns from 1999, the year Mulroney said he paid taxes on the money he took from Schreiber; banking documents and other records related to the safety deposit box Mulroney says he used to keep the money in the United States.

The ethics committee insists it is working on getting all the important documents from all the key players and that includes Brian Mulroney.

In other words, there should be more binders. Perhaps many, many more binders to come.
