When President Bush visited Canberra on 23 October 2003, Brown and fellow Senator Kerry Nettle interjected during his address to a joint sitting of the two Houses of Parliament.[13] During Bush's speech Brown and Nettle wore signs referring to David Hicks and Mamdouh Habib, two Australian citizens held at Guantánamo Bay, Cuba, at that time (Habib was later released without charge and Hicks served a prison term for providing material support for terrorism), following their apprehension by United States forces in Afghanistan and Pakistan respectively. Bush accepted the interjections with good humour but the Speaker of the House, Neil Andrew formally "named" Brown and Nettle. This meant that they were both suspended from the Parliament for 24 hours which prevented them from being present during a similar address from Chinese President Hu Jintao the next day.
