President Obama was greeted with protests against the proposed Keystone XL pipeline on Friday during a visit to South Dakota. A member of the Cowboy and Indian Alliance said activists were heeding Obama’s call on Americans to engage in politics.

Aldo Seoane: “I think it’s us enforcing our rights, our freedom of speech, and to be able to address the president. He actually made a statement encouraging people to seek change and to address it head on.”

Obama has delayed a final decision on the Keystone XL multiple times during his presidency. There are now reports he will wait until after Canada’s federal election in October so as not to be seen as interfering in Canadian politics. Canadian Prime Minister Stephen Harper has urged Obama to approve the pipeline.
