The fight against the so-called “Common Core” curriculum standards in public schools has attracted support from prominent conservative groups and leaders including Michelle Malkin, FreedomWorks and Texas Sen. Ted Cruz, who was one of nine Republican senators who signed a letter last month asking for legislation to prevent the federal Department of Education from pressuring states to adopt Common Core. An online petition says, “Instead of teaching critical thinking and problem solving, Common Core stresses the lowest common denominator, punishes achievement, and forces all students to conform to government standards.”
At 9 p.m. ET Thursday, activists launched a Twitter rally on the #StopCommonCore hashtag, and event described by Truth in American Education:
The #StopCommonCore Twitter Rally features a panel of experts who are planning on answering questions by the moderator, as well as taking live questions from Twitter users across the nation. The panelists are Shane Vander Hart (@shanevanderhart) of Truth in American Education, William Estrada (@will_estrada)  of Home School Legal Defense Association, Joy Pullmann (@joypullmann) of Heartland Institute, Ben DeGrow (@BenDegrow) of the Independence Institute, and Emmett McGroarty (@approject) of American Principles Project.
This rally is also being supported by Pioneer Institute (@pioneerboston), Americans for Prosperity(@afphq), Heartland Institute (@heartlandinst), Independence Institute (@i2idotorg), American Principles Project (@approject), FreedomWorks (@FreedomWorks), and  Home School Legal Defense Association (@hslda).
