Yoon says in connection with his last statement in the impeachment trial against him that it was a desperate attempt to get the public to understand the danger of the opposition-controlled parliament.
The country's constitutional court will decide whether Yoon should be formally removed from office, and the court is expected to give a decision on the matter in mid-March.
Yoon has denied doing anything wrong and blamed the political crisis on the opposition party, the Democratic Party.
His presidential powers were suspended when he was impeached on December 14, but if Yoon is removed, the country must hold new presidential elections within 60 days.
Yoon promises political reforms if he is allowed to return to his post.
A separate criminal trial is also underway against Yoon.
