Donald Trump has once again taken to Twitter to discuss his travel ban, which has been criticised by many.
Mr Trump's executive order has suspended the visas of travellers from seven predominately Muslim countries, while access for Syrian refugees has been blocked indefinitely.
Following this, Republican senators John McCain and Lindsey Graham said in a joint statement: “Such a hasty process risks harmful results.
“We fear this executive order will become a self-inflicted wound in the fight against terrorism.”
Trump hit back online, claiming the critics were "looking to start World War III."
American airports were left in chaos as Trump announced the ban, as scores of people affected by the ban were already on their way to America when the order was made public.
Many had to be held at airports, whilst some were not allowed to board flights or were removed from flights overseas.
But the President claims that the problems caused at airports were not a result of his ban.
The President has also called upon people to "study the world," after many have been outraged at the news and are holding protests.
The latest tweet was perhaps the most typical of Mr Trump, reminiscent of some of his bomastic rhetoric during the campaign.
