Georgia Rep. Doug Collins, an ardent ally of President Donald Trump and vocal opponent of his impeachment, is expected to announce he will challenge fellow Republican and newly appointed Sen. Kelly Loeffler for her seat this year, a Republican official said Monday. The decision by the four-term lawmaker could complicate the GOP’s chances of holding onto the seat as Republicans battle to retain their Senate majority in this November’s elections. Loeffler, 49, was appointed this month to the seat by Republican Gov. Brian Kemp to replace the retired Sen. Johnny Isakson, who left office due to deteriorating health.
