Livestock not native to the desert have grazed and trampled the plants tortoises like to eat, spreading unpalatable nonnative grasses in their wake.

"I didn't fully know what had happened. I felt enormous pain in both my legs; they were bruised and grazed," the 77-year-old former home secretary and health secretary wrote in the Sun on Sunday.

The most recent was in August, when a bullet grazed his back while he was with his partner, who was also injured.

In July, a gunman grazed his ear after shooting at the former president during a Pennsylvania rally.

“There was a group of poor Asian aunties that had all got pushed to the floor. They grazed their knees and they also snapped a few nails, too.”
