This has been done by a large group, probably financed by Soros or Obama or Hillary. And many of the reporters claim that President Trump's Tweets about violence encourage such to happen. But there is no evidence of Republican started violence. There has been much violence done to pro-Trump people and attendees to conservative speaker events in universities. This a last ditch effort for trying the change who rules the House of Representatives. It was not done by one persons or Republicans. The deliveries were done by individuals not with the UPS and for individuals who do not get mail directly. But if the latter happens, what good will happen because of the new leadership??? Seems most Democrats including most of the media just want to do whatever they can to stop President Trump from keeping his good promises. The Bible says we should be praying for our "kings". I pray daily for such and their families and advisers too. And I pray in response to many of the daily news reports, especially the tragedies since many think about the purposes of living at those times.
