Donald Trump Muslim immigration ban: US border patrol 'checking people's Facebook for political views'

US border agents are checking people’s Facebook pages for their political views before allowing them into the country, an immigration lawyer has claimed. 

Houston-based lawyer Mana Yegani said several green card holders, who have the right to live and work in the US, were detained by border agents at American airports hours after President Donald Trump signed an executive order banning immigration from seven countries in the Middle East and Africa. 

The ban affects travellers with passports from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen and also extends to green card holders who are granted authorization to live and work in the United States, according to a Department of Homeland Security spokeswoman.
