Giuliani walloped for claim Trump has constitutional duty to pressure Ukraine to probe Biden

Rudy Giuliani claimed President Donald Trump had a constitutional obligation to carry out the Ukraine scheme, and was quickly drowned in mockery.

The president's personal attorney jumped to an unusual legal conclusion based on Article II, Section 3 of the U.S. Constitution to defend Trump's efforts to pressure Ukraine into investigating Joe Biden -- which Giuliani is continuing to pursue this week in a visit to Kyiv.

"Presidential Legal Obligations 101," Giuliani tweeted. "Art 2, Sec. 3 of the US Constitution obligates the President to investigate and ask for investigations of corruption in countries we provide funds to. Who ever heard of a president being impeached for carrying out his constitutional mandate?"

Giuliani's tweet failed to persuade other Twitter users.
