US investigations into claims of Russian influence on President Donald Trump are "laughable," the Kremlin said on Tuesday.
"There have been so many such investigations that their significance has been devalued," Kremlin spokesman Dmitry Peskov said in comments carried by state news agency TASS.
The US House of Representatives' Judiciary Committee has begun a new probe into allegations of collusion with Russia during Trump's campaign for the 2016 presidential election.
The panal said Tuesday it is seeking documents from 81 individuals and entities, including Donald Trump Jr, as part of its inquiry, which will also focus on potential corruption and abuses of power.
"None of the previously launched investigations has yielded any serious findings. All were laughable," Peskov said. He refused to comment specifically about the House investigation, saying: "It is an entirely US affair."
Trump or his associates are facing several investigations. Chief among them is the probe by Robert Mueller, the special counsel who is focused on the Russian meddling in the 2016 presidential election and any links to Trump's campaign.
It remains unclear when the Mueller probe will wrap up, though the investigation has already led to indictments against Trump's inner circle, including Trump's long-time former personal lawyer Michael Cohen and ex-campaign manager Paul Manafort.
