David Axelrod actually said...
Donald Trump is president of the United States now. A heinous attack has occurred. I think most Americans looked at that with horror and he now has the responsibility to do something about it and I think he's going to find that people's patience are going to wear thin if his answer is, well, it's the last guy's fault.
Context
Axelrod emphasizes that Trump must take responsibility for the current situation in Syria rather than blaming Obama.
