The flag below is the US flag.
Notice that it has 50 stars in a staggered pattern. Even with this many stars, there are only about 3 rows of stars at the same height as the red stripe that touches the bottom of the blue union and the white stripe immediately above it.
Now check out the flag Brent Greer painted on his house. He has 7 rows of stars at the same height as two stripes, and they are in a rectangular pattern, meaning that, contrary to the Fox News headline, he did not paint the US flag on his house. He did not paint any recognizable flag whatsoever.
The closest I have been able to find to what he painted is this one, representing some fictional situation in which the Confederate States of America had conquered and incorporated the United States of America, yet still ended up with 50 states. This has a staggered pattern, though, and a white stripe extending to the bottom of the blue union.
