A bit more from TMZ:
The bomb squad is currently sweeping through Rush Limbaugh’s Palm Beach home after a suspicious package was discovered on scene.
According to local reports, Limbaugh’s security team discovered the package and notified authorities.
Story developing ...
It also sounded like the police actually requested the bomb squad too. The plot thickens...
I suspect it is just precautionary, but with the hate out there being voiced all over the net; perhaps someone or some group wanted to have Rush go down with Breitbart; the latter being referred to as a General today by the media, as his role in the conservative movement.
Security called so is reason for concern.
