Fox issues on-air apology for misleading footage of Palin crowds.

Following ThinkProgress’ report yesterday that Fox News had recycled old file footage of Sarah Palin rallies to assert that she is currently getting huge turnouts on her book tour, the network issued an on-air apology this afternoon. Fox’s Happening Now co-host Jane Skinner said it was mistake, but didn’t explain how it happened:

In the tease before the segment — the tease to commercial — we told you how those people were already lining up to meet Palin. The problem is, we didn’t actually show you the video we were referencing. Instead, we mistakenly aired what’s called file tape of Sarah Palin. We didn’t mean to mislead anybody in that tease. It was a mistake. And for that, we apologize.

Watch it:

The Swamp reported earlier that Fox News may take “serious disciplinary action” against control room staffers over the incident. The on-air apology made no reference to such action.
