Prime Minister Najib Abdul Razak's administration has been called the US' "errand boy" for remaining silent about President Donald Trump's travel ban on the citizens of seven Muslim countries.

"Malaysia is only an errand boy for Trump, and the wellbeing of the Islam community worldwide is not their concern... saving Najib and BN is more important to them," said Amanah international bureau chairperson Raja Kamarul Bahrin Shah Raja Ahmad in a statement today.
