US President Joe Biden refused on Monday to apologize for calling for the removal of his Russian counterpart Vladimir Putin from power, saying he expressed "moral outrage" and not "political change"..

"I was expressing the moral indignation I felt toward that person. I did not articulate a political change," said Joe Biden, quoted by Lusa.

Joe Biden also added that he is not concerned that his comments, made on Saturday during a trip to Poland, will increase tensions in the conflict in Ukraine.
