UPDATE: Nov. 6, 2015, 11:21 AM ET
President Obama is scheduled to deliver an official announcement at the White House today at 11:45 a.m. ET.
Multiple outlets reported Obama would reject the controversial Keystone XL pipeline during the address. Vice President Biden is also scheduled to attend, a White House statement said.
The decision caps a 7-year saga that became one of the biggest environmental flashpoints of Barack Obama’s presidency.
Killing the pipeline allows Obama to claim aggressive action on the environment. That could strengthen his hand as world leaders prepare to finalize major global climate pact next month that Obama hopes will be a crowning jewel for his legacy.
Yet it also puts the president in a direct confrontation with Republicans and energy advocates that will almost surely spill over into the 2016 presidential election.
Ahead of the address, Obama was scheduled to meet with Secretary of State John Kerry at 11 a.m.
