On his way back from his trip to the United Kingdom, Ireland and France, Trump tweeted that going to the Moon is old sh... stuff. He wants NASA to focus on Mars, which includes going to the Moon.
"For all of the money we are spending, NASA should NOT be talking about going to the Moon - We did that 50 years ago. They should be focused on the much bigger things we are doing, including Mars (of which the Moon is a part), Defense and Science!"
The line of about the Moon being a part of Mars had a lot of people/media calling him an idiot, because the Moon is not a part of Mars; but pump your brakes everyone, of course he meant it was a part of the Mars mission, which it will have to be, to get our chops back up and it will be a little stop over on the way. And that's what makes him sound like an idiot in that tweet, in order to go to the Moon as a part of the Mars mission NASA needs to "talk about" going to the Moon, which is what he tweeted three weeks prior to this.
