Twitter blocks Rep. Marsha Blackburn

According to Politico and AP, Twitter is barring a top Republican Senate candidate Rep. Marsha Blackburn from advertising her campaign launch video on the service because a line about her efforts to investigate Planned Parenthood was deemed "inflammatory." Really? It's inflammatory to investigate use of fetal tissue, but not to threaten to assassinate the president? https://apnews.com/0d8828bd7d204b40af61172628d0a7f6
