Acting Deputy Homeland Security Secretary Ken Cuccinelli is calling for a boycott of Greyhound after the bus company announced last week it would stop cooperating with federal immigration enforcement.

In a shock announcement last Friday, Greyhound announced that "it would notify the Department of Homeland Security that it does not consent to unwarranted searches on its buses or in areas of terminals that are not open to the public."

The transportation company cited customer and employee safety as the reason for the surprising change.

"It's a sad day to see something like this, and hopefully #BoycottGreyhound will pick up," Cuccinelli said Saturday on Fox News.

"This is not something they talked to us about before they made their public comment. So for us, it's ultimately about how we can all work together and the effectiveness of our law enforcement efforts," he explained.

Cuccinelli later said the DHS would engage in discussions with Greyhound about the policy change.

And just as Cuccinelli wanted, "#BoycottGreyhound" trended on Twitter on Saturday.
