A Republican state senator who punched a Democratic lawmaker in the head expressed regret, saying "that's not the way grown men solve their problems," but he said he won't immediately apologize.
Republican Sen. Charles Bishop claimed that Democratic Sen. Lowell Barron called him a "son of a bitch" in the Senate chamber on Thursday.
"I responded to his comment with my right hand," Bishop said.
Alabama Public Television tape captured the punch.
"I was raised in the woods of Arkansas and people don't say that about your mom," Bishop said.
The Senate divisions that derailed a White House-backed immigration bill â€” for now, at least â€” mirror the U.S. society's deep differences over the issue, according to polling data, lawmakers and analysts. Those gaps will challenge any effort to get the measure back on track.
While most Senate Democrats appeared to back the bill, several liberal members said it did too little to keep immigrant families together and protect jobs for U.S.-born workers.
The split in the Republican Party was more obvious. The issue pitted social conservatives, who insisted that illegal immigrants not be granted "amnesty" for entering the country unlawfully, against business groups hungry for willing workers in hotels, restaurants, construction sites and other comparatively low-wage, low-skilled workplaces.
The CIA ran secret prisons in Poland and Romania from 2003 to 2005 to interrogate detainees in its war on terror, European investigator Dick Marty said in a report released Friday.
The report, citing unnamed CIA sources, said top terror suspects Abu Zubaydah and Khalid Sheikh Mohammed were secretly held and interrogated in Poland, and that the "highest state authorities" in countries involved knew of the alleged detention centers.
The four-year U.S. military death toll in Iraq passed 3,500 after a soldier was reported killed in a roadside bombing in Baghdad. A British soldier was also shot to death Thursday in southern Iraq, as Western forces find themselves increasingly vulnerable under a new strategy to take the fight to the enemy.
The British ambassador to Iraq, meanwhile, signaled his government was ready to talk to those behind the abduction of five Britons in Baghdad last month. Iraqi officials have said they believe the Britons were taken by the Mahdi Army militia, which is largely loyal to the radical Shiite cleric Muqtada al-Sadr.
