In a statement Wednesday morning, former President George W. Bush congratulated former President Donald Trump and thanked President Joe Biden and Vice President Kamala Harris for their service.

"The strong turnout in this election is a sign of the health of our republic and the strength of our democratic institutions," Bush said.

Bush notably did not endorse a candidate or publicly reveal how he would vote. His daughter, Barbara Bush, canvassed in Pennsylvania for Harris last month, and is former vice president, Dick Cheney, said he was voting for Harris.

"We join our fellow citizens in praying for the success of our new leaders at all levels of government. May God continue to bless our great country," Bush said.

Democratic Rep. Susan Wild, who for six years has represented a toss-up congressional district in Pennsylvania’s Lehigh Valley, conceded Wednesday morning and congratulated state representative Ryan McKenzie.

In a statement, Wild congratulated McKenzie while calling it a "bitterly disappointing outcome."

"This is how American democracy works. It’s how we move forward," she said. "And it is absolutely crucial that candidates, in victory and in defeat, abide by this principle. You cannot only recognize the results of elections you win, no matter how much you may disagree with them."

Former President Donald Trump and Vice President Kamala Harris have not connected yet as of early this morning, Trump’s senior adviser Jason Miller said on ABC News’ Good Morning America.

“As of the last time I spoke with President Trump, they had not connected, but we'll see what happens today,” Miller said, going on to stress the message of unity.

“I think what President Trump said last night when he's up there on the stage was that he wants to heal the country. This is the time when we put aside the political divisions. We bring Democrats, Republicans, people who aren't necessarily even involved with politics together,” Miller said.
