The Republican governors of three states announced they will send state National Guard personnel to Washington, D.C., at the Trump administration's request. The big picture: The deployment of hundreds of additional troops, who will join the 800 already mobilized in the nation's capital, marks a major escalation in President Trump's takeover.

On Sunday night, South Carolina Gov. Henry McMaster and Ohio Gov. Mike DeWine both announced their respective deployment of troops to the capital.

At least 700 National Guard troops will be sent to Washington, D.C., nearly doubling the number of Guardsmen active in the capital.

President Donald Trump deployed 800 National Guard troops to the nation's capital as part of a crime crackdown in the city.

Trump's plan to address crime in D.C. calls for deploying National Guard troops along the National Mall overnight Wednesday into Thursday morning, according to a source.
