President Donald Trump launched a Twitter attack Saturday morning on San Juan Mayor Carmen Yulín Cruz for "poor leadership ability," saying she and others in Puerto Rico "want everything to be done for them when it should be a community effort."

Such a hateful, childish man. He is not a leader.

Trump thanking the Coast Guard while addressing a member of the Air Force.

TRUMP: What a job the Coast Guard has done throughout this whole — throughout this whole ordeal. They would go right into the middle of that — I mean, I don’t know, I wouldn’t want to be doing it, but I want to thank everybody. I want to thank the Coast Guard. They are special, special, very brave people.

And a lot of people got to see the real Coast Guard during this incredible trouble, and especially I think here and in Texas was incredible what they did. So thank you all very much. Thank you very much. We appreciate it. Really appreciate it.

Would you like to say something on behalf of your men and women?

AIR FORCE REPRESENTATIVE: Sir, I’m representing the Air Force.

TRUMP: No, I know that.
