German Paper Contradicts President in Call Scandal Germany's biggest-selling newspaper is challenging an assertion by the country's president that he didn't try to prevent it publishing a report on a controversial private loan. President Christian Wulff has faced intense pressure since it emerged that he left an angry message on the voicemail of Bild newspaper's editor-in-chief Kai Diekmann Dec. 12 - the day before the story appeared. Wulff insisted in a television interview Wednesday he hadn't tried to block the report and had merely asked for it to be delayed by a day so he could respond. But Diekmann expressed "astonishment" about that in a letter to Wulff on Thursday, seen by the AP. He says Bild wants to publish the text of the message but would like Wulff's approval "in the spirit of transparency you have spoken of."
