Federal minister Ismail Sabri Yaakob said he does not know what was in Idris Haron's head when the latter claimed the United States was trying to topple Prime Minister Najib Abdul Razak and the Malays.

Idris, who is the Malacca chief minister, had claimed last Sunday that the US was doing this through the Department of Justice (DOJ) lawsuits related to 1MDB.
