Biden says he's "just getting briefed" on developments in South Korea

 US President Joe Biden declined to weigh in on the unfolding events in South Korea after the country’s lawmakers blocked South Korean President Yoon’s martial law decree, saying he has yet to be fully briefed.

“I’m just getting briefed on it,” Biden told reporters when asked about South Korea after delivering a speech at the National Museum of Slavery in Angola.

Many in the Biden administration appear to have been caught by surprise by the turn of events.

“We are seriously concerned by what we are seeing develop,” according to a senior administration official.

Earlier in the day, a National Security Council spokesperson said: “The Administration is in contact with the ROK (Republic of Korea) government and is monitoring the situation closely.”
