US Rep. Dennis Kucinich, a vocal critic of the Bush administration's war in Iraq, plans to introduce articles of impeachment against Vice President Dick Cheney on Tuesday.
Kucinich, a Democrat who is again running for president, said Monday that he will hold a news conference in Washington to discuss his bid to oust Cheney. Kucinich spokeswoman Natalie Laber declined further comment.
Cheney spokeswoman Megan McGinn responded to Kucinich's announcement by saying that the vice president has served the nation honorably for almost 40 years.
"The vice president is focused on the serious issues facing our nation," McGinn said.
