He was impeached 12 March 2004 and Prime Minister KO Kun is now the acting President.
FWIW, The CIA World Factbook spells Roh's name both ways...
WASHINGTON (Reuters) - South Korea has been pushing the U.S. Central Intelligence Agency to change the way it spells President Roh Moo-hyun's last name, but the CIA is sticking to its guns, the embassy said on Sunday.
In an online directory and in its World Fact Book, a standard reference, the CIA spells it "No," rather than "Roh," the Korean leader's preference.
The embassy has sent the CIA three formal requests, one last year and two this year, as part of efforts to get the entire U.S. government to change its spelling, said Jeongsun Suh, the officer in charge of press and culture.
"Up to now, we didn't receive a response," he said.
