mess up

"What Alan Garten did here is a pretty significant mess-up and again, as you just appropriately stated, it corroborates everything that I said."

The prime minister has accepted he made a mistake but this mess-up is likely to stick with him.

“There was no conspiracy. This was a mess-up. This was a goof,” he said.

"But it's different for each mess-up, you know?!"

“I never got to say I’m really sorry that this happened, or I really own that this was a big mess-up on everybody’s part,” she said.
