In June 2013, May signed an order prohibiting Pamela Geller and Robert Spencer, two American bloggers who co-founded the anti-Muslim group Stop Islamization of America, from entering the United Kingdom on the basis that their presence would not be "conducive to the public good". The pair had been invited to attend an English Defence League march at Woolwich, where Drummer Lee Rigby had been killed earlier that year. The pressure group Hope not Hate led a campaign to exclude the pair, whom the Home Office described as "inflammatory speakers who promote hate".
