Biden's under-fire top aide Ron Klain suggests he could STEP DOWN this year as Dems blame him for pushing a woke agenda and 'creating a monster' out of the radical left wing of the party

• Klain, 60, has been grappling with a slew of reports blaming him for tensions between President Joe Biden and moderate Democrats
• He declined to give a timetable when asked how long he would stay on but Klain did point to two ex-Dem chiefs of staff who stayed in the role less than 2 years 
• 'It is a grinding job, there's no question about it. It takes a lot of stamina to do it. So we'll see how long it lasts,' Klain said
• Tuesday's report notes that Klain drew the anger of West Virginia Senator Joe Manchin, who said he opposed Build Back Better partially because of Biden staff
• Unnamed Democrats accused Klain of unfairly giving Congressional Progressive Caucus Chair Rep. Pramila Jayapal outsized influence in White House policy
