Guys, this is bad.

Donald Trump is giving the State of the Union, and he refused to shake the hand of Speaker of the House Nancy Pelosi.

Right before he delivered his address tonight, Trump greeted all the lawmakers in the room — but as many noticed right away, he did not shake Speaker Nancy Pelosi’s hand.

As the moment played out on CNN, Jake Tapper noticed and remarked, “It looks like she went to shake his hand and he did not — he did not take it.”

From CNN’s Manu Raju:

Pelosi reached out to shake Trump’s hand and Trump snubbed her

Welp, Pelosi just reached out to shake Trump's hand and he turned away. Pelosi visibly winced.

SOTU begins. Pelosi offers to shake hands with Trump: As is customary.
Classless creep, he refuses.

No smile from Donald Trump as he walked in. Did not shake hands with Speaker Pelosi.

I know it seems like Trump snubbed Pelosi’s handshake but what you have to remember is tiny elfin hands get tired easily

Donald Trump just refused to shake Nancy Pelosi’s hand.

He’s clearly scared of her.

Trump knows Pelosi is just getting started dismantling him.
