Germany's interior minister and head of Bavaria's Christian Social Union party has reportedly threatened to quit both positions over Chancellor Angela Merkel's migration policies.
Horst Seehofer reportedly said he wants Germany to turn away migrants who have already been denied asylum in Germany or have previously sought asylum elsewhere in Europe.
Last week, Merkel and other European leaders agreed to start limiting migrant asylum seekers' movement around Europe. It's called "secondary migration."
That deal didn't specify what measures EU states can take to stop secondary migration, though. And Germany's interior minister says it isn't enough.
If Seehofer resigns, it could mean the end of the decades-old alliance between Merkel's Christian Democratic Union of Germany party and Seehofer's CSU party.
Seehofer told reporters early Monday morning that he agreed to meet with Merkel's party again before making his final decision.
