"God gave us grace on November 8, 2016, to change the course we were on," Lindell said. "God had been taken out of our schools and lives, a nation had turned its back on God. I encourage you to use this time at home to get back in the word. Read our Bible and spend time with our families."

Like other American companies, Minnesota-based MyPillow is refocusing its production to make face masks for health care workers on the frontlines of the pandemic.
"We started then to find out what we could make," Lindell said last week while appearing on "America's Newsroom" with host Ed Henry. "We worked with the administration. They have a coalition to what kind of masks are need out there. Obviously, we specialize in cotton and we found out different materials that they didn't want -- latex ... and stuff. So, finally, we got the final prototype three days ago."
The masks will be shipped to several states, he said.
