Osama Bin Laden Thought Joe Biden Was Incompetent, Hated Fox News

Osama bin Laden wanted Joe Biden to become president of the United States because he believed he was incompetent, new al Qaeda documents show.

"Obama is the head of infidelity and killing him automatically will make [Vice President Joe] Biden take over the presidency," bin Laden wrote, according to The Washington Post's David Ignatius. "Biden is totally unprepared for that post, which will lead the U.S. into a crisis."

Administration officials said Friday that the plot, which aimed to kill Obama and Gen. David Petraeus, never got off the ground, the Post reports.

The documents also show that al-Qaeda was no fan of Fox News.

"As for Fox News let her die in her anger,” the group's American-born media advisor, Adam Gadahn, wrote to bin Laden, in discussing where to send a video. Later, in comparing American television networks, he wrote, "From a professional point of view, they are all on one level -- except (Fox News) channel, which falls into the abyss as you know, and lacks objectivity, too.”

Previous releases of al Qaeda documents showed bin Laden stressing over the terrorist organization's finances.
