I think he wiped an irritant on his eye with his finger. He put it on the corner of the eye first,and then wiped the finger across the bottom of the eye toward his nose. He then put his finger up to his nose to get full effect. As with all else he does, this was a fraud too.

That’s exactly what I think. He had something on his fingers that he rubbed on his eyes.

He then put his finger up to his nose to get full effect. There, that's better.

He probably had a small slice of onion in his pocket, touched the onion with this left hand to his left eye. It appears that he was only crying from one eye. How is that possible?

The long pause was to simulate being choked up but when he spoke his voice was firm.
