Minister Umbridge has this to say: "It is clear to us that Mr. Potter has some kind of role in Headmaster Dumbledore’s death. It is inconceivable that a wizard with the power and experience of Headmaster Dumbledore could fall so quickly when confronted by Death Eaters in his own school. To the Ministry, all the evidence indicate someone close to Dumbledore betrayed him. We asked Mr. Potter to present himself for questioning to ascertain his role and offer him the chance to prove his innocence."
