"Despite what you have heard from the FAKE NEWS, I had a GREAT meeting with German Chancellor Angela Merkel".
President Trump reiterated his stance that European allies need to meet their end of the bargain to continue benefiting from the military alliance.
Trump shares a different opinion when it comes to immigrants and previous year, during his presidential campaign, the US President had taken pot shots at Merkel of allowing refugees from Syria to take shelter in Germany.
Trade has topped the agenda during Mr. Trump and Ms. Merkel's first face-to-face meeting.
Though the two didn't shake hands while cameras were in the room, the president did shake her hand at other times during her visit - here's a handshake upon her arrival.
"So that's not going to prevent us from concluding agreements and indeed this would then qualify as a bilateral agreement between the European Union and the United States if we had it", she added.
Mr Trump said he "very seldom" regrets anything he tweets, brushing off questions about his claims without evidence that his predecessor, Mr Obama, wiretapped him during last year's presidential campaign.
Prior to his inauguration, Trump declared North Atlantic Treaty Organisation "obsolete" but has since modified his stance, telling European leaders the alliance remains of strategic importance. Germany now spends around 1.2 percent of their GDP on defense with plans to increase it in the coming years, but that money doesn't go to the United States.
Besides the United States (at 3.36 per cent of GDP), only Britain (2.17 per cent), Poland (2.01 per cent), Estonia (2.18 per cent) and Greece (2.36 per cent) now reach the goal, according to North Atlantic Treaty Organisation estimates for 2016.
"Germany and America are connected by values of democracy, freedom and respect for the law and the dignity of man, independent of origin, skin color, religion, gender, sexual orientation or political views", Merkel said in a statement shortly after Trump's election victory.
Trump expressed appreciation for Merkel's assurance that Germany is committed to increasing its military spending.
Those comments appear to contradict a series of tweets by the US President earlier this month, in which he labelled former president Barack Obama a "bad (or sick) guy" and said a "good lawyer could make a great case" out of the claims.
Reporters even questioned whether or not there would be a handshake, to which Angela asked Donald, "Do you want to have a handshake?" "We are trying to address the areas where we disagree....and find a compromise".
