According to AP, Mack said US President Barack Obama “should be asking for the end of Chavez"s regime,” for supposed violations of human rights, instead of buying oil from Venezuela, which supplies close to 10% of US oil consumption.

Mack said buying oil from Venezuela, “keeps the US State Department hostage”, and for that reason, he requested the replacement of the South American country for another supplier.

“We need to focus right away on replacing foreign oil coming from tyrants like Chavez, for reliable and stable allies like Canada,” the Republican congressman stated.

Mack has been characterized by his frequent attacks against Venezuela and he has requested several times to include the South American country in the US list of governments supporting “terrorism.”

The congressman was accused in November 2010 by the Bolivian President Evo Morales of making a public call for the assassination of President Chavez, during an meeting of the extreme right in the US.

Mack's statements were made in the midst of a military intervention of colonizer powers, led by the United States, in Libya, which owns over 40% of African oil reserves.

The pretext used for the invasion was an alleged violation of human rights committed by the Libyan leader Muammar Al Gaddafi.
