President Trump again singled out Chicago while announcing he was deploying the National Guard to Washington, D.C. Monday.

In New Mexico’s most populous city, National Guard troops are listening to the police dispatch calls, monitoring traffic cameras and helping to secure crime scene perimeters, tasks not usually part of the job.

Crouched down, Thaliya Martinez fidgeted with her camera lens, preparing for a day of photographing aircraft at Chicago’s annual Air & Water Show. Martinez, a freelance photographer and member of the Army National Guard, said she aspires to be a pilot one day.

Mayor Muriel Bowser sought to reassure residents in the nation's capital, adding that the National Guard deployment was unnecessary.

The presence of National Guard troops in Washington, DC, is expected to expand Wednesday evening, according to a White House official, as President Donald Trump’s takeover of the city’s law enforcement continues to take shape.
