WASHINGTON (AP) A spokeswoman for President Donald Trump says allegations against Missouri Governor Eric Greitens are “very concerning.” During a briefing at the White House Friday, reporters asked White House spokeswoman Sarah Sanders about a letter from three Missouri state senators – all Republicans – to Trump, urging the president to ask Greitens to resign.

Prominent Missouri lawmakers, Republicans and Democrats, have called on Greitens to step down over allegations that he slapped, grabbed and shoved a woman with whom he had an extramarital affair in 2015, before his election.

Greitens has said he’ll continue to serve and that allegations of violence or sexual assault are false.

Sanders said she didn’t have an official response but says the allegations are something the White House is taking very seriously.
