President Donald Trump's personal attorney Sunday warned of a legal battle if special counsel Robert Mueller subpoenas Trump to testify in the ongoing Russia investigation.

"A subpoena for live testimony has never been tested in court as to a president of the United States," Jay Sekulow said on ABC's "This Week," adding: "It’s hard-pressed to see why they need the president’s testimony.”


"The president has been clear that he wants to interview … his legal team is concerned," according to Sekulow, noting the legal team's "inclination" is for Trump not to sit down with Mueller.

The remarks came within an hour after the president tweeted about the June 2016 meeting at Trump Tower at which his oldest son, Donald Trump Jr., and senior campaign officials met with Russian representatives.

The president tweeted Sunday the meeting was "to get information on an opponent," though his son initially claimed it was primarily about Russian adoptions. Reports have indicated that the Trump team was promised information about Hillary Clinton, then the presumptive Democratic nominee.

“The question is, How would it be illegal?" asked Sekulow of host George Stephanopoulos. "You have to look at what laws, rules, regulations, statutes are purportedly violated here."
