**Dumbledore lied to Minister Fudge in OoP**

From OoP, chapter 28

> 'Dumbledore's Army, Cornelius,' said Dumbledore, still smiling as he
> waved the list of names before Fudge's face. 'Not Potter's Army. Dumbledore's Army.'
>
> 'But - but -' Understanding blazed suddenly in Fudges face. He took a horrified step backwards, yelped, and jumped out of the fire again. 'You?' he whispered, stamping again on his smouldering cloak.
>
>'That's right,' said Dumbledore pleasantly.
>
> 'You organised this?' 
>
>'I did,' said Dumbledore.
>
>'You recruited these students for - for your army?
>
> 'Tonight was supposed to be the first meeting,' said Dumbledore, nodding. 'Merely to see whether they would be interested in joining me. I see now that it was a mistake to invite
> Miss Edgecombe, of course.' 
>
>Marietta nodded. Fudge looked from her to Dumbledore, his chest swelling.
>
> 'Then you have been plotting against me!' he yelled.
>
>'That's right,' said Dumbledore cheerfully.
