The Prime Minister's Chief of Staff has stepped down in light of the Senate expense scandal.
In a statement issued Sunday morning, Nigel Wright says Stephen Harper has accepted his resignation.
The Prime Minister's Office said earlier this week that Wright personally paid off $90,000 in inappropriately claimed housing expenses for Senator Mike Duffy, who later stepped down from Conservative caucus.
Wright says his actions were intended "solely to secure the repayment of funds,'' which he considered to be in the public interest.
He says he did not tell Harper how Duffy's expenses were repaid, either before or after the fact.
