Etta Vs. Beyoncé

Per the Huffington Post, Etta did not like B singing her song, At Last, at the President's Inaugural Ball, which was what a month ago... I guess better late then never. Check out her talking about President Obama and B at a recent Seattle concert... my only issue with Etta is, President Obama more than likely did not pick the song Beyoncé sang as he had to prep for... you know TAKING OVER THE OVAL OFFICE! So I am not sure when Etta says, he is not her President... did she not vote for him as she had issues with him in the past while he was campaigning, or is this about B singing her classic hit and him dancing to it. I do not see the crime here on his part.
