Kinzinger has served since 2010, and ran unopposed in 2018.Trump’s tweet was a summary of comments made on Fox News by evangelical pastor Robert Jeffress, an ardent supporter of the president’s who has made inflammatory remarks in the past about Muslims, Catholics, gays and Mormons.Trump’s tweet is an escalation of his rhetoric after House Speaker Nancy Pelosi announced that House Democrats would open an impeachment inquiry into the president over allegations that he pressured the Ukrainian president to investigate former Vice President Joe Biden and his son Hunter. Joe Biden is vying for the Democratic nomination to challenge Trump in the 2020 election. The allegations were first surfaced in a whistleblower complaint that was made public last week. The revelation spurred a majority of House Democrats to support an impeachment probe, which has also gained support from American voters in a series of recent polls. Neither Rep. Kinzinger’s office nor the White House immediately responded to requests for comment.
