Kim Jong-un has committed to denuclearising the Korean peninsula.
"While I am glad the president and Kim Jong Un were able to meet, it is hard to determine what of concrete nature has occurred", said Senate Foreign Relations Committee Chairman Bob Corker, Tennessee Republican.
Schumer said Trump's meeting with Kim gave "a brutal and repressive dictatorship the worldwide legitimacy it has long craved".
A joint declaration after the first meeting between a USA president and a North Korean leader called the summit "an epochal event of great significance in overcoming decades of tensions and hostilities between the two countries and for the opening up of a new future".
Trump had a 40-minute private talk with Kim (with translators present), followed by an expanded bilateral talk and working lunch.

Previously, Kim visited the White House last week for a meeting with 45 about Alice's situation and prison reform in general. Trump commuted Johnson's life sentence on Wednesday , following Kardashian's high-profile campaign.
Asked if he had a message for the North Korean people, Trump said, "I think you have somebody that has a great feeling for them".
But Rocky Kim was dismissive.
Rocky Kim fled the peninsula in the early 2000s, shortly after his father starved to death.
That's a big concession to make, and one that caught many people by surprise.
And what stunned many observers was a shift in rhetoric that made Trump sound like a full-blown North Korea apologist.

Trump and USA allies may need some moisturizer more than Pruitt from the severe tariff chafing they experienced at the G7 summit. State news agencies quoted Kremlin spokesman Dmitry Peskov as saying, "We are putting the emphasis on other formats".
Loosening tensions, and therefore potentially decreased sanctions, could lead to an economic boom for this Chinese city, which facilitates the passage of about 70% of goods entering North Korea. "Nothing there is a freedom".
Trump said next week he will get together with national security adviser John Bolton and his team to go over details of the next steps. One of peace. Two men, two leaders, one destiny.
Trump also agreed to halt joint military exercises between the US and South Korea on the Korean Peninsula, though that decision seemed to surprise both Seoul and the Pentagon.
The North Korean account is no longer available on Twitter.
Not in the written but in last-minute verbal agreements made during the summit is a commitment by North Korea to the destruction of a major missile engine testing site.
Trump said that "Chairman Kim has an opportunity to be remembered as a leader like no other".

The last time North Korea cooperated in a recovery effort between 1990 and 2005, only 229 sets of remains were recovered. North Korea and the USA appear to be warming up relations after spending most of 2017 on the brink of nuclear war.
"There's no doubt that he is a very brutal dictator, but at the same time we do have to work with what we have, rather than wishing that he was different".
