Jessica Chasmar writes in the Washington Times:

Leader of Russia’s Communist party, Gennady Zyuganov, speculated
Wednesday that the death of Venezuelan president Huge Chavez was part
of a plot by the United States to infect Latin America with cancer.
did it happen that six leaders of Latin American countries which had
criticized US policies and tried to create an influential alliance in
order to be independent and sovereign states, fell ill simultaneously
with the same disease?” Zyuganov said on Russian state television, RIA
Novosti reports.

Irony being is that I certainly recall the Soviets nee Russians poisoning their expatriates within the last ten years.
