By Jonathan Allen JENA, Louisiana (Reuters) -A U.S. immigration judge ruled on Friday that Palestinian activist Mahmoud Khalil can be deported, allowing President Donald Trump's administration to proceed with its effort to remove the Columbia University student from the United States a month after his arrest in New York City.

Columbia University graduate student Mahmoud Khalil can be kicked out of the U.S. as a national security risk, an immigration judge in Louisiana found Friday during a hearing over the legality of deporting the activist who participated in pro-Palestinian demonstrations.
