The group, which includes several First Nations grand chiefs and regional chiefs, say they do not accept the apology she gave last month and insist she must resign.

The Senate Ethics committee says Beyak has acknowledged the wrongs of her past conduct and committed herself to improvement after taking a four-day program to educate herself about Indigenous history

The Senate has voted to suspend Sen. Lynn Beyak a second time over derogatory letters about Indigenous Peoples posted on her website.

Sen. Yuen Pau Woo, leader of the Independent Senators Group, says that her apology Monday to fellow senators on her racism towards Indigenous Peoples wasn't enough for her to avoid another suspension.

The letters she received and published online, which were in support of Canada's residential school system, also included suggestions that Indigenous Peoples and their culture were inferior.

The reported comments were made when Beyak identified herself as Metis and reasoned this was because her parents adopted an Indigenous child, who became her sister.

Lynn Beyak's colleagues ousted her from the upper chamber temporarily last spring after condemning as racist several letters she had posted to her website.

Beyak, who represents Ontario, posted those letters among many others supporting her view that some Indigenous people had positive experiences in residential schools.

"What constituency is asking for that again, except for the most hardened partisan Conservatives?" said Liberal MP Seamus O'Regan. "I mean, who looks at it now and thinks that Lynn Beyak was an inspired choice? And where does it leave us (in future) -- Sen. Ezra Levant?''

Senate officials erased the letters posted online after Beyak refused to do so herself.
