Absolutely. Trump went back on his word, as he does time and again.
It's just like when Trump promised to release his tax returns, and is now fighting their release tooth and nail.
It's just like when Trump claimed he'd love to testify for the Mueller Investigation, and then subsequently refused to testify and even his written answers seemed extremely lacking. Answering "I don't remember" 30 times seems to be at odds with his claims of "I have the best memory in the world".
Trump couldn't talk about Mueller's investigation into Russian hacking and meddling without calling it a "witch hunt", despite the clear evidence of Russian interference which it found.
