GUATEMALA CITY (AP) — Guatemalan President Jimmy Morales is expelling the head of a U.N. anti-corruption commission that is investigating the president's campaign financing.

A video posted Sunday on the government's Twitter site shows Morales declaring Ivan Velasquez "non grata" and ordering him to leave the country immediately.

The commission was created 10 years ago to fight corruption in the country and it has been key to prosecuting senior government figures, including past President Otto Perez Molina and former Vice President Roxana Baldeta, who are both imprisoned.

The commission and prosecutors are now questioning financing of Morales' 2015 campaign.
