Donald Trump raged at Hillary Clinton for "copying" his signature airplane rallies and criticized her for taking a day off campaigning.
"Do people notice Hillary is copying my airplane rallies - she puts the plane behind her like I have been doing from the beginning," Trump tweeted.
He continued in a subsequent tweet: "Hillary Clinton is taking the day off again, she needs the rest. Sleep well Hillary - see you at the debate!"
The Republican presidential nominee has become known for holding rallies in front of his giant Trump-branded Boeing 757, and on Monday his Democratic rival talked to press while standing before her plane.
