President Trump and North Korean leader Kim Jong Un signed a document on Tuesday stating that Pyongyang would work toward "complete denuclearization of the Korean Peninsula"-- a historic concession, which was one of the requirements the U.S. sought at the summit in Singapore.

Senator Lamar Alexander (R-TN), chair of  the Senate Health, Education, Labor and Pensions Committee joins Fox News Radio's Guy Benson and Marie Harf to discuss the North Korea Summit and more. 

Assessment on the summit: Well, it's a hopeful beginning and I think its a good opportunity for Americans of whatever persuasion to just take a deep breath step back and hope the President succeeds. I mean this has been the toughest problem for every president for the past 20 years and we don't know whether this will work or not but its a good start and let's hope the president succeeds.  (00:30)

On if North Korea agreements should come to Congress:  It should come to Congress one way or the other for a treaty. We need stability on these issues. If President Trump comes to an agreement with North Korea that needs to come to Congress (1:16)

On status of a bill curbing President's power on tariffs: I'd like to see Senator Porter get a vote on his amendment in the defense bill that we're debating in congress right now. I agree with President Trump on taxes, on judges, on regulation of Obamacare, but not on tariffs. That's a big mistake to put tariffs on aluminum and steel.  (1:58)

On the opioid crisis legislation: Well, number one its bipartisan and we unanimously passed a bill out of our committee which has 23 members from Elizabeth Warren to Rand Paul to deal with the opioid crisis. We expect it to be on the floor this summer.  (3:41)

On survey among Republican colleagues on their support of legislative proposals: Well, I can tell you the first, we're painfully aware that only eight years in the last 86 since 1932 have the Republicans had both the President and the Congress and if there's one more thing we can pass with 51 votes we wanna do it.
