Stephen Colbert said Donald Trump is now “doing party tricks” after the former president asked for someone in his rally audience to give him a pen.

When the pen landed several feet away, Trump walked over, bent down, picked it up, and returned to the microphone for a dig at President Joe Biden.

“You think Biden can bend down like that? I don’t think so!” Trump said as the audience cheered.

“This is where we are as a country,” Colbert said in disbelief. “The presidency of the United States could well come down to which old man can pick up a pen.”

Colbert envisioned how the “scintillating” debates might unfold.

“Which one of you gentlemen can climb into this doorless bathtub unassisted?” he asked.
