President Obama will deliver a speech from the White House at 12:15 p.m. EST today, following one of the most shocking U.S. elections in modern political history.

His comments comes after Hillary Clinton’s concession speech, which she delivered from New Yorker Hotel’s Grand Ballroom following her unexpected loss to Donald Trump on Tuesday night.

According to the White House, Obama already called Trump to congratulate him on his victory in becoming the president-elect and invited him to meet at the White House on Thursday. White House spokesman Josh Earnest says the meeting is to discuss the presidential transition.

Trump campaign manager Kellyanne Conway said Obama called Trump while he was speaking to his supporters in New York, and so Trump called him back after he left the stage. She said the two had what she described as a “very nice talk.”
