Rep. Liz Cheney (R-Wyo.) and Sen. Rand Paul (R-Ky.) are engaged in a Twitter feud, with Cheney claiming Paul's motto is "terrorists first" and Paul accusing the House Republican Conference chairwoman of "warmongering. Both Republicans are arguing with each other over which one actually stands with - and has the support of - President Trump. Cheney, resurfacing a 2015 tweet from Trump in which he called the libertarian-leaning senator and then-GOP presidential rival a "spoiled brat without a properly functioning brain," tweeted that "no truer words were ever spoken."
