Prosecutors repeat need for president to be questioned 'no later than Wednesday'

Prosecutors on Monday questioned two former key presidential aides over allegations they helped a shadowy confidant of President Park Geun-hye meddle in state affairs and secretly visit her office.

Park has been engulfed by a scandal that centers on Choi Soon-sil, who is accused of using her personal ties with the president to coerce major companies to donate millions of dollars to nonprofit foundations Choi then used for personal gain.
