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.
