RICHMOND, Va. (AP) _ A conservative minister announced he’s joining the fight for the Republican nomination to challenge Democratic U.S. Sen. Tim Kaine in 2018. E.W. Jackson announced his campaign Monday on The John Fredericks Show radio program. The lawyer-turned-preacher ran unsuccessfully for lieutenant governor in 2013. He joins Corey Stewart, a former state campaign chairman of President Donald Trump, and Del. Nick Freitas, as announced candidates. Jackson on Monday previewed a possibly contentious fight with Stewart for the nomination, suggesting Stewart supports tax increases. Stewart said both claims were “ridiculous.” Jackson’s fiery rhetoric added a touch of drama to his 2013 race. He compared Planned Parenthood to the Ku Klux Klan and said former President Barack Obama may be an atheist or a Muslim.
