The Canadian Senate is an important part of the Government of Canada, but now some senators are being investigated to find out if they took money they weren’t entitled to.

A senator’s job is to give the final approval to a bill before it becomes law.

Some Senate members have been accused of taking money for things that are not covered by their Senate budget.

The expenses of senators Mike Duffy, Pamela Wallin, Mac Harb, and Patrick Brazeau are being looked at.

Mike Duffy used to be a journalist before he was appointed to the Senate. In the Senate, he represents Prince Edward Island.

He was accused, along with the other senators, of taking money for things that he had no right to.
