The Canadian Taxpayers Federation has put Alberta Premier Alison Redford at the top of its provincial government "naughty" list for staying in a Washington hotel that charged $876 a night.
The federation says Redford's posted expense claims also show she charged taxpayers for $22 coffees and a $31 hamburger while in the U.S. capital.
The CTF later said on its website that Redford's office had clarified that the $22 claimed for coffees was for pots of coffee.
Other Redford expenses in 2013 included an almost $8,000 airfare to New Brunswick and a $6,000 flight to Chicago.
The taxpayers group also singled out Thomas Lukaszuk, who was deputy premier and advanced education minister until a recent cabinet shuffle.
It points out he spent more than $9,000 on a trip to Europe and claimed 17 flights between Edmonton and Calgary.
Justice Minister Jonathan Denis heads the "nice" list for — quote — "having the most boring expense claim two years' running."
Alberta has an expense disclosure policy which directs senior government officials to post their expenses online.
