I want to know the answer to the following question:
Who visited the Ukraine while the protests were taking place?
All the background I'm provided with is that "In late February, large public rallies took place in Kiev to protest the election laws, on the eve of the March 26 elections to the USSR Congress of People's Deputies, and to call for the resignation of the first secretary of the Communist Party of Ukraine, Volodymyr Scherbytsky, lampooned as "the mastodon of stagnation.". Is that enough to answer the question?
