(Fox News) President Trump signed a proclamation Wednesday night to send the National Guard to the southern border immediately, a senior White House official told Fox News, in response to what the administration described as an “unacceptable” flow of drugs, criminal activity and illegal immigrants.

Homeland Security Secretary Kirstjen Nielsen said at the White House press briefing that the signing would be done in conjunction with governors and that the administration hoped the deployment would begin “immediately.”

“Despite a number of steps this administration has taken…we continue to see unacceptable levels of illegal drugs, dangerous gang activity transnational criminal organizations and illegal immigration flow across our border,” she said.
