Angelina Jolie is cross. And it's not with Brad Pitt about that beard, rather she's miffed about US president, Barack Obama.

Angelina's written an open letter for , in which she addresses issues in Sudan and the fact.

That Obama's administration 'has not yet announced any serious moves' to deal with bringing corrupt Sudanese leaders to justice.

In the piece titled Justice Delayed is Not Justice Denied, she writes: 'I believe President Obama... will do (his) best to bring peace to the region.'

But she goes on to write: 'How is the Obama administration's approach to Sudan an evolution of justice?

In addition, when the administration says it intends to work to 'improve the lives of the people of Darfur.

I would like to know what that means, besides the obvious point that their lives could hardly get worse.'

'On this Human Rights Day - the same day President Obama receives his Nobel Peace Prize - we must also remember those who have been deprived of their rights.' She recently revealed that she and Brad often have debates about President Obama.

Now that we know what she thinks of the political side of things, we wonder what she'll have to say about First Lady Michelle Obama's fashion from yesterday's Nobel Peace Prize ceremony where Barack was honoured.
