Former senior advisor to President Obama, David Axelrod, explained on Morning Joe Friday morning that all of the president’s changes to his signature health care law were both expected and necessary.

“There’s no doubt that this law is going to have to be perfected along the way – they’re going to have to make adjustments along the way,” Axelrod said. “They’re not violating the spirit of the law, all of those provisions are going to move forward.”

Axelrod challenged Republicans who questioned the president’s authority to bring their case to court.

“We hear this from members of Congress, ‘it’s illegal, he’s violating the constitution’ and so on,” he added. “Why don’t they go down to the courthouse and test that proposition if they’re so confident about that?”

According to Axelrod, White House staffers knew that Obamacare would have to be adjusted after it passed Congress.

“I think that from the very beginning, when the president contemplated this – and there was a lot of discussion in the White House about this and I was involved in those discussions – it was very clear it was going to be tough, it was going to be complex, that there was going to be a period when this law was being implemented where there would be a lot of consternation about elements of it and that it was going to have to be adjusted along the way,” he insisted.

Rather than oppose the legislation, Axelrod suggested that the best thing for lawmakers to do was to keep working together to make the law better.

“A majority of people say let’s move forward and fix it along the way and that’s exactly what the president will do,” he said. “I think that they just have to press forward on this.”
