Mitt Romney, Rick Santorum and Newt Gingrich slammed Obama this week over his refusal to approve the pipeline as the Republican presidential hopefuls continued to try to win conservative support on the issue.

"Now, you wouldn't know it from listening to some of these folks who are running for office -- I won't mention their names, you know who they are -- but producing more oil here in our own country has been, and will continue to be, a key part of my energy strategy," Obama said Wednesday in Maljamar, N.M., a day ahead of his speech in Cushing.

TransCanada has said it expects to put the pipeline in service by 2015. Despite Obama's delay, the company has said it anticipates its Presidential Permit application will be approved in the first quarter of 2013.

As for the Cushing extention, TransCanada began operations there in February 2011. Construction is expected to resume there in June.
