US President Donald Trump said he "gave up nothing" at a summit with Russian President Vladimir Putin, suggesting he made no concessions or agreements that might be detrimental to US interests.

"When you hear the Fake News talking negatively about my meeting with President Putin, and all that I gave up, remember, I gave up NOTHING, we merely talked about future benefits for both countries. Also, we got along very well, which is a good thing, except for the Corrupt Media!" Trump tweeted.
