Quote from : Harry Potter and the Order of the Phoenix Movie

Sirius Black: The latest intelligence is that Fudge doesn't want you trained in combat.
Ron Weasley: Combat? What does he think, that we're forming some sort of wizard army?
Sirius Black: That's exactly what he thinks. That Dumbledore is assembling his own forces to take on the Ministry. He's becoming more paranoid by the minute. The others wouldn't want me telling you this, Harry, but things aren't going at all well with the Order. Fudge is blocking the truth at every turn, and these disappearances are just how it started before. Voldemort is on the move.
