President Trump's pick for Army secretary could withdraw from consideration as early as this week, according to a report, following a slew of accusations from liberal groups over comments he's made regarding LGBT issues and Islam.

Sources close to the nomination process believe Tennessee state Sen. Mark Green may not have enough support from Republicans and Democrats to be confirmed, CNN reported.

Green, a conservative Christian, is under increasing fire from the political Left over past statements opposing gay marriage, transgender bathroom rights and teaching Islam in public schools.

On Monday, Rep. Steny Hoyer, D-Md., the No. 2 Democrat in the House, called his past statements "disgusting" and joined 31 fellow Democrats in urging the Senate to reject the nomination for what they called a history of homophobia and transphobia.

At least six liberal advocacy groups have also opposed Green in recent weeks.

Republicans, meanwhile, have been mostly silent on the issue. Sen. John McCain, in a brief interview with USA Today, said he was bothered by Green's past statements.

"We are getting some questions from both Republicans and Democrats on the Armed Services Committee," said McCain, chairman of the Senate Armed Services Committee. "I think there are some issues that clearly need to be cleared up.

"Some of the comments that have been attributed to him obviously are very concerning."

An adviser to Green told CNN that the possibility of Green withdrawing was "completely, absolutely untrue."

If he does withdraw, Green would be the second nominee to take himself out of contention for the job. Trump's first pick, Vincent Viola, withdrew due to problems disentangling himself from his business interests.
