'He looks like he could take me': Biden tells heckler to 'shush up' - but backs off when he sees him - then threatens to 'expire' Republicans who don't back his healthcare plans

President Joe Biden took on a heckler who interrupted his speech at the D.C. train station, then joked that the man could probably best him in a fight.

Biden grew fiesty immediately after touting provisions in his American Rescue Plan that had the 'biggest investment in childcare ever.'

At that point a man briefly interrupted his remarks, pegged to 'care workers recognition month.'

'I tell you what - You want to come make a speech or shush up, okay?' Then, Biden added, 'He looks like he could take me,' drawing a laugh from the crowd of supporters.

He quickly moved on and proceeded with his remarks.  

President Joe Biden said it was time to 'expire' Republican lawmakers who allowed an expanded child tax credit expire

Biden couldn't help but offer remarks about the station he used to commute home to Delaware for 36 years, where he said it was time to 'expire' Republicans who allowed an expanded child tax credit to lapse.

Biden held an official event at Union Station, which is down Pennsylvania Avenue from the White House, where he heralded home care workers and blasted at Republicans for going after the Affordable Care Act.

Biden couldn't resist a train during remarks at the colossal station. 'Thirty-six years I commuted from the state of Delaware here every single day,' he said. 

'When I got elected I was 26, 29 years old,' said Biden, 81, retelling the tragic story of the death of his wife and daughter. 'Thank God I had a family and a lot of friends, older family members like me' who could help care for his sons.

Biden spoke about investments at the 'care economy' at Union Station, which he used to commute home to Delaware for decades

'I couldn’t afford caregiving. God’s truth,' Biden said. 'Look, careworkers represent the best of who we are in America. We leave nobody behind,' he said. 

Biden hammered congressional Republicans for letting an expanded child tax credit expire. It is credited with bringing down child poverty. 

'Our Republican friends let that expire,' he said. 'Well, we've got to expire a couple of them politically.

He also blasted them for attempts to repeal the ACA. 

'They want to terminate the Affordable Care Act. Terminate it. Guess what? Killing millions of Americans, taking health care insurance, stripping others of services like home care,' he said. 'By the way – you know how many times they've tried to take out the Obamacare? Forty-nine times. They can keep trying but they're not going to get it done.'
