President Donald Trump made history by becoming the first sitting U.S. President to walk across the border into North Korea. And it was all set up in a tweet.

In a tweet, Trump announced he would meet North Korean leader Kim Jong Un at the DMZ, the demilitarized zone or border that separates North Korea from South Korea.

Hours later, on Sunday, June 30, Trump met North Korean leader Kim Jong Un inside the DMZ and shook hands before Trump stepped across the border from Panmunjom, South Korea into North Korea.

“Good to see you again. I never expected to meet you at this place,” a translator quoted Kim, as the two men shook hands. Then Kim invited Trump to step across the border, telling him, “You are the first U.S. president to cross the border.”

Photographers jockeyed for position at the Demarcation Line to record history when Trump walked into North Korea early Sunday morning. The epic moment briefly united Democrats and Republicans back in the U.S.

Many U.S. lawmakers said the meeting between the two world leaders was a positive move toward world peace. They hoped the meeting would restart stalled nuclear disarmament talks.

Afterwards, Trump and Kim turned and walked back across the border to the South Korean side where they spoke with South Korean leader Moon Jae-in. Then Trump and Kim met for an hour behind closed doors.

The White House released a transcript of the meeting in which Trump and Kim said they are committed to the “complete denuclearization” of the Korean peninsula.

Trump’s advisor Ivanka Trump and her husband, U.S. Senior Advisor Jared Kushner were there to witness history.

Initially, members of the White House press pool were locked out of the meeting by Kim’s aggressive security detail. There are reports that new White House press secretary Stephanie Grisham was injured trying to make room for members of the press to capture the historic meeting.

Grisham was bruised when an “all-out brawl” erupted between Kim’s security and members of the press (watch videos below). She bravely shoved aside two of the guards, and shouted “Go! Go!” to the photographers who scrambled past her.

CNN’s Jim Acosta tweeted that Grisham suffered “bruises” in the scuffle.

Melania Trump’s former spokeswoman was promoted to the job after former press secretary Sarah Huckabee Sanders left to become a stay-at-home mom to her three children.

Once referred to as the “world’s most dangerous border,” the DMZ was established as a neutral zone between North Korea and South Korea at the end of World War II. The Military Demarcation Line (MDL) is a stone border about 6 inches high and 12 inches across. The actual border (chain link fences topped with razor wire) stretches from sea-to-sea and is heavily patrolled by forces on both sides.
