 ABC's Selena Wang at the White House. Those balloons filled with trash and manure once again being floated between North and South Korea. It appears to be retaliation. The balloons began flying after South Korea dropped leaflets. This is ABC News. My wife and I both, we ended up mildly sick for a few months and the nasal congestion was probably the worst part. I had like a post nasal drip, just super congested all the time. We were taking everything we possibly could, but nothing really worked.
