Facebook has banned multiple ads released by a pro-life organization in support of Republican Senate candidates.

The Susan B. Anthony List said Thursday that Facebook banned its ad supporting Matt Rosendale, the Republican nominee in Montana's 2018 U.S. Senate race.

"This is getting ridiculous," the organization wrote on Twitter, asking Sheryl Sandberg, the chief operating officer of Facebook," Is #ProLife speech welcome on your platform or not?"

BREAKING: @Facebook just banned ANOTHER one of our ads – this time in Montana. This is getting ridiculous, @SherylSandberg. What's the deal? Is #ProLife speech welcome on your platform or not?#MTSen @MattForMontana #IVoteProLife✅ Watch the ad Facebook banned: pic.twitter.com/skSGlrglIG — Susan B. Anthony List (@SBAList) November 1, 2018

The Susan B. Anthony List then tweeted an email the organization received from Facebook. The email said the pro-life ad "doesn't comply" with Facebook's advertising policies and will not be active until the Susan B. Anthony List edits it accordingly.

The ad supporting Rosendale was the Susan B. Anthony List's second of the day to be banned by Facebook.

BREAKING: This morning Facebook banned our 30-second ad exposing pro-abortion @PhilBredesen in Tennessee and supporting #ProLife Marsha Blackburn for Senate. Watch the ad Facebook censored: pic.twitter.com/BHlklKqD0Q#TNSen @VoteMarsha #IVoteProLife✅ — Susan B. Anthony List (@SBAList) November 1, 2018

The other ad supported Rep. Marsha Blackburn (R., Tenn.) against her Democratic opponent, Phil Bredesen, in Tennessee's Senate race.

That ad was later restored.

[THREAD] UPDATE: Facebook has restored our #ProLife ad they banned this morning, saying: "This ad does not violate Facebook's policies and should never have been disapproved. We’re sorry for this mistake – the ad has been restored and is now running on Facebook." [1/3] — Susan B. Anthony List (@SBAList) November 1, 2018

Susan B. Anthony List president Marjorie Dannenfelser issued the following statement after the Tennessee ad was banned:

SBA List has faced repeated censorship over the last few weeks and now our ad supporting Marsha Blackburn has been disapproved, even after more than 90,000 had viewed it. Facebook must immediately stop its censorship of pro-life speech. All the information presented in our ads has been factual, if surprising, to those unwilling to face the reality of pro-abortion extremism. Facebook is censoring the truth and political free speech.

The organization released another statement in response to the Montana ad being taken down.

Last week, Facebook removed two other pro-life ads put out by the Susan B. Anthony List—one set to run in Arizona, the other in Iowa—the Washington Examiner reported.

Blackburn currently holds a seven-point lead in the RealClearPolitics polling average for Tennessee's Senate race, while the same average shows incumbent Montana Sen. Jon Tester (D.) leading Rosendale by four points.
