Trump saw the mid-term elections for the US Congress as a "historic step backwards".
At the same time, the American leader claims that in the future the country will be stronger than before.
The president announced this on the Social Truth social network.
"As a result of the last election, America has taken a huge step backwards in its history. But fear not, we will come back stronger and stronger than ever," wrote Donald Trump.
In the midterm elections on November 3, Americans elected all 435 members of the House of Representatives and 35 senators.
