More than a month after President Trump deployed the U.S. military to Los Angeles amid immigration sweeps, the troops have largely disappeared from public view.

Roughly 4,000 National Guard troops and 700 Marines had been deployed. It wasn’t immediately clear how long the rest would stay in the region.

The Trump administration is cutting the number of National Guard members in the Los Angeles area by 2,000 after their deployment last month in response to immigration protests, the Pentagon announced Tuesday.
