Global aluminum giant Alcoa's(AA) CEO Klaus Kleinfeld accused lawmakers of acting like children.
"(The) last thing we need is those types of disruptions," Kleinfeld told CNN. Kleinfeld warned that it's not the right time to be in a political crisis especially since the U.S. economy is just in the process of recovering.
He said lawmakers should open a "serious discussion on fiscal reform," but first raise the debt ceiling, which will increase the nation's ability to borrow more to cover what it owes.
"I think with grownups -- that typically happens," Kleinfeld said.
