South Korean President Yoon Suk Yeol’s dramatic fall is building public support for his biggest political rival — Lee Jae-myung — to run as the nation’s next leader if fresh elections happen.

President-elect Donald Trump plans to launch a mass deportation operation targeting millions of immigrants living in the U.S. illegally and with temporary protections once he takes office on Jan. 20, a challenging initiative that could split apart families and affect U.S. businesses.

A summons for Mr Yoon to appear for questioning over alleged insurrection was delivered to the presidential residence on Tuesday but returned, the agency quoted a joint investigation team as saying. If he responds to the summons, it will be the first time in history that a sitting president appears before prosecutors as a suspect.
