"We find ourselves once again in agreement with Senator Edwards, this time with his decision last evening to endorse Senator Barack Obama," the union said in a statement, according to the AP. "And thus today, the United Steelworkers enthusiastically endorses Senator Barack Obama to be the next president of the United States."

"All of us," the statement said, "including we hope Senator Clinton for whom we have the utmost respect, must now do everything we can to ensure that Barack Obama is the next president of the United States. Now is the time for contention and division to cease, and for us to unite behind the changes for which Senator Obama and our members are calling."
