ABOVE: Liberal MP wonders why the PM has been silent on the comments made by John Williamson

OTTAWA – Another Conservative MP is criticizing a caucus colleague over racial remarks about temporary foreign workers.

Devinder Shory, who represents a Calgary riding, calls New Brunswick MP John Williamson’s comments racist and says he is outraged.

I am extremely disappointed by the racist comments that were made by MP Williamson http://t.co/a2i98UPFOm #cdnpoli #diversity #pluralism — Devinder Shory (@NortheastShory) March 10, 2015

Williamson told delegates at a conference in Ottawa on Saturday that it makes no sense to pay “whities” to stay home while companies bring in “brown people” as temporary foreign workers, the political website iPolitics reported.

The New Brunswick MP posted a series of tweets Saturday to apologize for the language he used in talking about the controversial federal program.

1/3 Today I used offensive and inappropriate language regarding the Temporary Foreign Workers Program. For this I apologize unreservedly. — John Williamson (@JohnW_MP) March 7, 2015

But those apologies didn’t appear to quell the anger of Williamson’s colleagues.

Deepak Obhrai, another Calgary Conservative, used Twitter to criticize Williamson, saying years of outreach work with ethnic communities had gone down the drain as a result of the comment.

Very disturbed by Williamson's race based comments. Foolish statement damages all of us. Years of hard work down the drain #cdnpoli #yyc — Deepak Obhrai (@deepakobhrai) March 8, 2015
