It is one of the first major bills to land on Trump's desk since becoming president in January, but the legislation imposes restrictions on Trump himself.
In a statement last week, Russia's Ministry of Foreign Affairs said Congress' almost unanimous approval of the sanctions bill indicates that "in certain circles" of USA politics "Russophobia and the course of open confrontation with our country have become entrenched".
Trump Jr later released a string of emails showing the meeting with the Russian lawyer had been set up in a bid to acquire damaging information about rival presidential candidate Hillary Clinton. After passing the House and Senate with a veto-proof majority, the bill was going to become law with or without Trump's signature.
The bill was signed privately at the White House on Wednesday as the ceremony closed to the press, but according to official a statement is forthcoming.
"The president did not draft the response", Sekulow said. The statement that was released on Saturday was released by Donald Trump Jr., I'm sure in consultation with his lawyers.

Throughout the investigation, the president denied any involvement in or knowledge of the meeting.
Sekulow's Meet the Press comments may have been meant to insulate the president from involvement in Trump Jr.'s efforts to collude with Russian Federation.
US President Donald Trump has reportedly dictated a misleading statement in which his son said a meeting between him and a Russian lawyer was centered on adopting Russian children. Trump told the members he makes such frequent appearances at the property in Bedminster, New Jersey, because: "That White House is a real dump".
She also rejected the Post's claim that Trump dictated it directly. "This was. unnecessary", one of the president's advisers told the newspaper.
In a statement to ABC channel, Russian Deputy Foreign Minister Sergei Ryabkov had said, "I think this retaliation is long, long overdue".
