Of all the odd things president Trump does, his handshake is among the most notorious.
Few people have worked out how to outmanoeuvre the Trump handshake. He refused to shake Angela Merkel's hand altogether, and appeared to simply grab Theresa May's. Justin Trudeau and Emmanuel Macron faired slightly better, but the president's handshake method remains a strange enigma.
This makes it even odder that Trump decided to mock democratic presidential candidate Beto O'Rourke's "crazy" hand movements. After the former Texas congressman announced his bid for the 2020 democratic presidential nomination, Trump said during an Oval Office meeting:
I think he's got a lot of hand movement.
I've never seen so much hand movement. I said, 'Is he crazy or is that just the way he acts?'
Trump referenced a video of O'Rourke from Iowa, where he appeared particularly impassioned.
I've actually never seen anything quite like it.
Study it. I’m sure you'll agree.
This criticism is particularly odd given Trump's inability to shake hands properly, but also his own animated and highly unusual way of gesturing with his hands.
The president did not say whether he viewed O'Rourke or former vice president Joe Biden as a stronger opponent in 2020, saying:
Whoever it is, I'll take him or her on.
O'Rourke served three terms in Congress before an unsuccessful bid to unseat republican Ted Cruz in last year's mid-term elections.
