Ted Cruz, R-Texas, on Saturday shared a celebratory message for Juneteenth, a new federal holiday, celebrating the emancipation of Black slaves after the Civil War.”Today is Juneteenth, a special celebration of the fact that our country strives each and every day to make good on its promise to protect the inalienable right to life, liberty, and the pursuit of happiness for all men and all women who are created equal,” he tweeted.The tweet emphasizes the freedoms listed in the Declaration of Independence — the same freedoms Americans fought for during the Civil War — rather than the political differences the country is currently grappling with.WHAT IS JUNETEENTH?
