US congressman halts Cheney impeachment campaign

US Democratic presidential candidate Rep. Dennis Kucinich, a frequent Iraq war critic, canceled plans to introduce articles of impeachment against Vice President Dick Cheney on Tuesday, citing Cheney's health problems. Cheney was taken to his doctor's office for an ultrasound of a blood clot in his leg Tuesday. He later returned to the White House to resume his normal schedule, said Megan McGinn, a spokeswoman for the vice president. "Until the vice president's condition is clarified, I am placing any action on hold," the Ohio congressman, who also unsuccessfully sought the Democratic presidential nomination in 2004, said in a news release.
