(CNN) - Is Colin Powell set to make a long-anticipated endorsement?
The former Secretary of State under President Bush, who has been coy about who he will support this November, will appear on NBC's Meet the Press this weekend, the network has announced.
Rumors have long swirled that Powell, the first African-American Secretary of State, is leaning toward backing Obama.
NBC is staying mum on what Powell will say: "[He] will break his recent silence and share his views on a variety of important issues," the network said.
A source close to Powell wouldn't say if an endorsement would come Sunday.
"Stay tuned," the source said.
Powell suggested last month he had yet to make up his mind.
The election of an African-American president “would be electrifying,” Powell told a George Washington University audience, “but at the same time [I have to] make a judgment here on which would be best for America.
Watch: Powell: I'm undecided
“I have been watching both individuals, I know them both extremely well, and I have not decided who I am going to vote for. And I'm interested to see what the debates are going to be like because we have to get off of this ‘lipstick on a pig’ stuff and get into issues,” he said.
