Democratic presidential candidate Sen. Bernie Sanders (D-VT) said Tuesday that President Obama faces an “unprecedented level of obstructionism” from Republicans.

“Literally on the day that Obama was inaugurated, Republicans came together and said ‘What are we going to do? ‘ And what they concluded is, ‘We’re going to obstruct, obstruct, obstruct and make it as difficult as he could to do anything,'” Sanders said during a CNN town hall.

“Now we have had to fight through that and I’ve been at the president’s side time and time again,” Sanders said. He pointed to Obama’s fight with Republicans over appointing a new Supreme Court justice and said that it’s,”nothing more than the continuous and unprecedented obstructionism that President Obama has gone through.”
