Editing Terry Mercer (section)

==As Senator==
A long-time fundraiser and organizer for the [[Liberal Party of Canada]], Mercer was National Director of the Liberal Party during much of [[Prime Minister of Canada|Prime Minister]] [[Jean Chrétien]]'s tenure as party leader. Mercer was appointed to the Senate representing [[Nova Scotia]] by Chrétien in November 2003, shortly before the Prime Minister's retirement. 

In February 2013, Mercer became a subject of criticism for having spent the most out of any senator in the previous year.<ref>{{Cite web|url=https://atlantic.ctvnews.ca/meet-terry-mercer-canada-s-most-expensive-senator-1.1157273|title=Meet Terry Mercer, Canada's most expensive senator|website=CTV News Atlantic|access-date=November 15, 2019}}</ref>

With the [[Senate Liberal Caucus]] facing losing official [[Parliamentary group|parliamentary caucus]] status in 2020 with a third of its caucus facing mandatory retirements on their turning age 75, Senator [[Joseph A.
