“That statement of President Trump’s is rich. He’s president now, he’s commander-in-chief,” Kaine told CNN’s “New Day."

“[Trump’s] got to put on his big boy pants and own up to the job. And remember, when President Trump was just Donald J. Trump, back then he was urging President Obama not to do anything in Syria.”

Trump said Tuesday that the reported use of chemical weapons by forces loyal to Syrian leader Bashar Assad was a “consequence” of Obama’s foreign policy.

“Today’s chemical attack in Syria against innocent people, including women and children, is reprehensible and cannot be ignored,” he said in a statement. "These heinous actions by the Bashar al-Assad regime are a consequence of the past administration’s weakness and irresolution.”

Trump did not say how the U.S. would respond to the attack, which is considered the worst chemical weapons strike within Syria in years.

Trump repeatedly urged Obama not to intervene in the Syrian civil war in 2013 on Twitter.

“AGAIN, TO OUR VERY FOOLISH LEADER, DO NOT ATTACK SYRIA – IF YOU DO MANY VERY BAD THINGS WILL HAPPEN & FROM THE FIGHT THE U.S. GETS NOTHING!” Trump tweeted in September 2013.
