Donald Trump's former White House press secretary Sarah Sanders will announce plans on Monday to run for governor of Arkansas, a source familiar with the situation said on Sunday.
Sanders will announce on video her intention to seek the Republican nomination for the November 2022 election, the source added.
The current governor, Republican Asa Hutchinson, is constitutionally barred from seeking a third term.
Sanders served as Trump's second press secretary, having replaced Sean Spicer in 2017. She resigned in 2019 to return home to Arkansas.
Meanwhile, the coming second impeachment trial of former US President Donald Trump on a charge of inciting the deadly storming of the Capitol has aggravated a rift among his fellow Republicans that was on full display on Sunday.
At least one Republican, Senator Mitt Romney, said he believed the trial, which could lead to a vote banning Trump from future office, was a necessary response to the former president's inflammatory call to his supporters to "fight" his election defeat before the Jan. 6 attack.
Ten Republicans joined the House of Representatives in voting to impeach Trump on a charge of inciting insurrection, and the House is to present the charges to the Senate on Monday. Leaders of the narrowly divided Senate agreed to start the trial in two weeks, leaving time to confirm some of President Joe Biden's Cabinet nominees and possibly address his call for a fresh round of stimulus for a coronavirus-hammered nation.
"The article of impeachment that was sent over by the House suggest(s) impeachable conduct," Romney, a frequent critic of Trump who voted to convict during the first impeachment trial, told Fox News on Sunday. "It's pretty clear that over the last year or so, there has been an effort to corrupt the election of the United States and it was not by President Biden, it was by President Trump."
The night after Trump's supporters stormed the Capitol - an attack that left five dead, sent lawmakers into hiding and delayed Congress by a few hours in its duty to certify Biden's election win - multiple Republicans condemned the violence.
The 38-year-old Sanders is the daughter of Republican former Arkansas Governor Mike Huckabee. She left the White House on good terms with Trump and supported his failed re-election bid.
