As expected, Trump and his team have denied any wrongdoing, with the president repeatedly referring to the allegations against him as a "witch hunt".
Starr made the argument that Trump, in using the word "hope" when he told former FBI Director James Comey that he wanted the investigation into former National Security Advisor Michael Flynn over, was basically saying, "Golly, I sure wish this would go away".
Trump's questions are best directed at his Department of Justice, who have the power to investigate Clinton.
Trump, who tweeted earlier Thursday that the investigation was "the single greatest WITCH HUNT" in United States political history and is being led "by some very bad and conflicted people", tried to turn the conversation to the 2016 Democratic presidential nominee, Hillary Clinton.

"He did not dismiss the investigation or curtail the investigation".
The tweets came after a Washington Post report that former FBI Director Robert Mueller, the special counsel overseeing the probe into Russian interference in the 2016 election, is also looking into whether Trump attempted to obstruct justice.
Trump was alluding to the former secretary of state's handling of her private email server, an issue that dogged the Democratic nominee's presidential campaign since before it officially began.
