Johnson warns Mall of America patrons

“If anyone is planning to go to the Mall of America today, they’ve got to be particularly careful,” Johnson said.

“There will be enhanced security there, but public vigilance, public awareness and public caution in situations like this is particularly important, and it’s the environment we’re in, frankly,” he said.

His comments come as the Mall of America implements new security measures — some of which the mall said in a statement would be noticeable to shoppers.

“The thing that, frankly, is frustrating to me — when I go to the Senate, they say, ‘It’s not us, it’s the House, go over to the House side and talk to them,'” Johnson said. “I go to the House and they say, ‘We passed our bill, it’s the Senate.'”

“We have four or five working days to get this right,” he said.
