The suspension of Donald Trump’s latest travel ban has been indefinitely extended by a US federal judge in Hawaii. In a lawsuit, Judge Derrick Watson says the ban would harm the island’s tourism and its ability to recruit foreign students and workers. The judge’s earlier temporary restraining order has now become a preliminary injunction that has a more longterm effect. This ruling means the US President cannot enforce the ban on six mostly Muslim countries while the suspension is contested in court. President Trump’s executive order on March 6 tried to impose a 90-day ban on people arriving in the US from Iran, Libya, Somalia, Sudan and Yemen, plus a 120-day ban on refugees. An earlier version of the order had been issued in late January and prompted protests and widespread confusion at airports. That ban, which also included Iraq, was blocked by a judge in Seattle.
