During the 2016 Republican presidential primary, then-candidate Donald Trump repeatedly called rival Sen. Ted Cruz (R-TX) a liar -- and also mocked his wife's appearance and insinuated that his father may have been involved in the plot to assassinate President John F. Kennedy.
And, as Toronto Star reporter Daniel Dale points out, Cruz ended his presidential bid in 2016 by calling Trump "utterly amoral," a "pathological liar" and a "narcissist at a level I don't think this country has ever seen."
Despite this, however, Cruz has agreed to write an essay praising Trump as part of Time Magazine's series on the most influential people in the world.
"President Trump is a flash-bang grenade thrown into Washington by the forgotten men and women of America," begins Cruz's essay, which is filled with slavish praise for the president. "The fact that his first year as Commander in Chief disoriented and distressed members of the media and political establishment is not a bug but a feature."
Given that Trump has still never apologized for mocking Heidi Cruz's appearance or for spreading baseless conspiracy theories about Cruz's father, many Twitter users heaped scorn on Cruz for so shamelessly sucking up to someone who has treated him so terribly.
