MINNEAPOLIS (AP) - Minnesota's congressional delegation is split on overriding President Barack Obama's planned veto of the Keystone pipeline project.

Keystone supporters are unsure if Republicans, who control the House and Senate, can rally the two-third majorities needed to undo a veto. First proposed in 2008, the pipeline would connect Canada's tar sands to Gulf Coast refineries.

Reports say Sens. Al Franken and Amy Klobuchar and Reps. Keith Ellison and Betty McCollum, all Democrats, plan to vote against an override.

Republican Reps. Tom Emmer, John Kline and Erik Paulsen and Democratic Rep. Collin Peterson will vote to override.

Democrat Rick Nolan won't say and Tim Walz did not immediately respond to a request for comment.
