another can of worms

What’s more, one of the town’s fat cats decides to sponsor a Green Meadow High Hall of Fame — another can of worms.

Of course, this opens up another can of worms.

The officials are another can of worms entirely.

But such an argument could open another can of worms for the city: It’s illegal to use public resources, such as city staff time, on political campaigns.

“The owners can try to prevent kneeling, but they open another can of worms,” said Randal Maurice Jelks, professor of African and African-American studies and history at the University of Kansas.
