What did Donald Trump do today?

He claimed he'd never heard of Wikileaks.

Today, Ecuador expelled Julian Assange from its London embassy, where he has spent the last seven years as a refugee. He was immediately arrested by British police. The United States is among several countries seeking to prosecute Assange for crimes ranging from rape to computer espionage.

Wikileaks was one of the ways that the Putin regime in Russia used to distribute the e-mails it stole from the Democratic National Committee as part of its efforts to throw the election to Trump.

At a joint press conference with the President of South Korea today, Trump said, "I know nothing about WikiLeaks. It's not my thing."

Trump has talked publicly about Wikileaks at least 164 times. More to the point, Trump's longtime friend and advisor Roger Stone acted as a go-between for the Trump campaign and Wikileaks, which Trump himself was aware of.

Who cares?

• It's bad if the president has ties to international criminals.

• Past a certain point, lying becomes pathological.

• Demanding that people you want power over ignore obvious lies is a form of abuse.
