Philippine President Ferdinand Marcos Jr on Thursday distanced himself from the impeachment of his estranged Vice President Sara Duterte, saying the executive branch of government cannot have a hand in it.

The lower house in the Philippines impeached Vice President Sara Duterte Wednesday, accusing her of a wide range of crimes that included plotting to assassinate the president, large-scale corruption and failing to strongly denounce China’s aggressive actions against Filipino forces in the disputed South China Sea.

The Philippine Senate president says the impeachment trial of Vice President Sara Duterte will begin after Congress reopens in June and will be done fairly to avoid a repeat of a 2001 impeachment proceeding that stalled and sparked massive protests that forced a president to step down.
