Two National Guard members are in critical condition after a “targeted attack” in Washington, D.C., on Wednesday, according to D.C. Mayor Muriel Bowser, leaving one suspect injured and the troops in critical condition.

Donald Trump has made National Guard deployment in US cities a recurring theme. Here’s how those efforts have played out around the country.

​More than 2,000 National Guard troops deployed to Washington in August after President Trump took federal control of the city’s police and mobilized the troops in what he described as a crackdown on crime. Since then, the troops have patrolled metro stations and tourist areas, and picked up trash around the National Mall.

President Donald Trump says Wednesday's attack on two National Guard members near the White House highlights the dangers of lax migration policies.

Two DC National Guard soldiers have been shot by a metro station near the White House in Washington, D.C. The conditions of the soldiers shot by the Farragut West metro station are not known. Details of the shooter are not known.

Staff Sgt. Jacob Hill, with the Alabama National Guard, died while assigned to the Washington, D.C., mission earlier this month.
