( CNN) Despite his last-minute petitions and hopes, former Trump campaign adviser George Papadopoulos will still have to start his 14 -day prison sentence on Monday for keep lying to federal examiners in the Russia probe.

The judge who sentenced him, however, denied both of his requests on Sunday, saying Papadopoulos hadn't filed any tribunal appeals within the window he was allowed and devoted a firm nod that the office of special counseling, which prosecuted Papadopoulos, has acted correctly.

Papadopoulos gave up much of his rights to appeal under his plea agreement, which he cut with the special counsel's office last year.
