"Single greatest scam" President Trump on impeachment

President Trump in a video posted on his Twitter account Saturday, said that, "What's going on now is the single greatest scam, in the history of American politics. The president continued in his video to say, "they're trying to stop me, because I'm fighting for you."

Earlier on Saturday, President Trump was greeted by protestors chanting "impeach" outside his Trump National Golf Club in Sterling, Virginia.

Ukraine must investigate the activities of U.S. presidential candidate Joe Biden's son to establish whether his role in a Ukrainian gas company complied with the country's laws, Mykola Azarov, Ukraine's former prime minister, said in an interview.

Azarov did not specify to which Ukrainian laws he was referring.

Hunter Biden's role in the company, Burisma Holdings Limited, is in focus after the White House published a memo showing U.S. President Donald Trump asked his Ukrainian counterpart, Volodymyr Zelenskiy, in a July phone call to get prosecutors to look into his activities. Zelenskiy agreed.

"It's a fact (his directorship and fees) and not made up. It should be investigated so that the 'i's can be dotted and the 't's crossed," Azarov told Reuters.

A spokesperson for Joe Biden's campaign declined to comment on Azarov's investigation call and none of Hunter Biden's critics have provided any evidence that he broke Ukrainian law.
