"I stand with the people gathered across the country tonight defending our values & our Constitution. This is not who we are," Clinton tweeted.

The tweet came amid backlash over Trump's order handed down Friday that bars Syrian refugees indefinitely and halts the resettlement of all refugees for four months as the administration reviews its vetting process.

The order also denies entry for 90 days for individuals from seven Muslim-majority countries: Iraq, Iran, Somalia, Sudan, Syria, Libya and Yemen.

A bipartisan group of lawmakers has denounced the executive action over the weekend, as the Trump administration defended the directive and Trump insisted during remarks in the Oval Office that it was not a "Muslim ban."
