Donald Trump's administration is "actively looking at" suspending habeas corpus - the right of a person to challenge their detention in court - one of the US president's top aides has said. Last week, another judge ordered a Columbia University student detained over his advocacy for Palestinians be released after a petition on habeas corpus grounds. CNN reported, citing unnamed sources, that Trump was personally involved in the discussions around suspending habeas corpus. Trump himself has not mentioned the suspension of habeas corpus, but has said he would take steps to combat injunctions against his actions on deportation. The section of the US Constitution which includes the suspension of habeas corpus grants its powers to Congress and not the president.
