More damaging details have emerged in the personal finance scandal surrounding German President Wulff. Chancellor Merkel says she remains supportive, but would like to see him address unanswered questions.

The scandal swirling around German President Christian Wulff is several weeks old by now. But it still shows no signs of abating. Indeed, this weekend yet more details emerged pointing to Wulff's less-than-impeccable personal finances.

According to a document seen by SPIEGEL, Berlin film financier David Groenewold paid the cost of an upgrade for a Sept. 2008 luxury hotel stay for Wulff and his wife Bettina during a visit Oktoberfest in Munich. At the time, Wulff was still governor of Lower Saxony.

Groenewold also took on the costs of child care for the couple's infant son during the trip to the annual beer festival, but Wulff repaid him later in cash. Wulff's lawyer responded to the allegations, saying merely that his client had received a bill for his hotel stay. Because Wulff had also been in Munich on official business, he submitted the bill to the Lower Saxony state chancellery and the state Christian Democrats (CDU).
