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.

Khalil, 30, was the first international student arrested in recent weeks amid an unprecedented crackdown by federal immigration authorities.

A US judge has ruled the Trump administration can deport Mahmoud Khalil, a Columbia University graduate detained last month over his role in pro-Palestinian protests.
