A session of the Iraqi Parliament erupted in an uproar on Wednesday as lawmakers clashed over how to respond to the continuing detention of an Iraqi television reporter who threw his shoes at President Bush during a Baghdad news conference earlier this week, people attending the parliamentary meeting said. As Parliament began to discuss legislation on the withdrawal from Iraq of armed forces from nations other than the United States, a group of lawmakers demanded that the legislature instead take up the issue of the detained journalist, Muntader al-Zaidi, 29. After his shoes narrowly missed Mr. Bush's head at the news conference on Sunday, Mr. Zaidi was subdued by a fellow journalist and then beaten by members of the prime minister's security detail. The legislative session became so tumultuous that it prompted the speaker of Parliament, Mahmoud al-Mashhadani, to announce his resignation, according to The Associated Press. A spokesman for Mr. Mashhadani, Jabar al-Mashhadani, refused to confirm whether the speaker had tendered his resignation, although he would not deny it. Some in Parliament say the government should release Mr. Zaidi immediately, while others say the judiciary should decide his fate. How badly injured Mr. Zaidi was by members of Prime Minister Nuri Kamal al-Maliki's security detail is not clear. He has not appeared in public since his arrest, and his family members and his legal representatives say they have not been permitted to visit him. On Wednesday, Mr. Zaidi was scheduled to appear before a judge, but it was unclear whether that happened. Dhiya al-Saadi, one of Mr. Zaidi's lawyers, said Wednesday that he was not sure whether Mr. Zaidi had appeared before a judge. As part of the Iraqi legal system, a judge typically determines whether bringing formal charges against a suspect is warranted, criminal lawyers in Iraq said. Mr. Zaidi faces up to seven years in prison if he is charged with and convicted of offending the head of a foreign state.
