The mayor of Phoenix on Wednesday called on US President Donald Trump to postpone a rally he was scheduled to hold on Tuesday in the city, saying it was too soon after a violent white supremacist rally in Virginia. 'I am disappointed that President Trump has chosen to hold a campaign rally as our nation is still healing from the tragic events in Charlottesville,' Mayor Greg Stanton said in a statement posted on Twitter. 'It is my hope that more sound judgment prevails and that he delays his visit,' Stanton said.
