The NDP have officially removed Christopherson from his position as vice chair of an important multi-party standing committee of the House of Commons.
On Monday, Christopherson defied his own caucus by supporting a motion against a controversial federal summer jobs program that requires applicants to check a box affirming that their core mandate respects the values of the Charter of Rights and Freedoms, including abortion rights.
Although firmly pro-choice, Christopherson believes the new rules for the Canada Summer Jobs program are an attack on people's freedom of conscience and right to dissent.

I think the correct tweet was that the party hurt themselves. Nobody knows procedure and rules better than @DaveChrisMP He is a fearsome force for good when it comes to respect for parliamentary rules and this is essential when you're the opposition.
