Meek Mill could have his probation revoked this morning, and it appears it's because he took a trip without permission.
Meek's on probation from a drug and gun conviction back in 2009. According to court docs, as of November 1, 2015, he was required to obtain a travel voucher before leaving Philly.
The judge ordered Meek to appear in court Thursday morning, for a probation violation.

Reading between the lines, it seems Meek may not have gotten permission to attend the AMAs in L.A. on November 22nd. 
If Meek screwed up, he could be sent to prison. This wouldn't be the first time he served time for violating probation. It happened last year and he was sent to jail for several months.
