"So @DonaldJTrumpJr testified 3 times now for hours on end about a meaningless 15 min meeting that resulted in nothing. I am still waiting for Hillary to be called to testify for Uranium One, Clinton Foundation, and her selling out America as Sec of State," Kirk tweeted Wednesday afternoon.

Eric Trump retweeted it less than an hour later.

Trump Jr.'s meeting with the Russian attorney alongside Jared Kushner and former campaign chairman Paul Manafort has become a central point in the multiple investigations into possible collusion between the Trump campaign and Russia.

Emails released by Trump Jr. ahead of a possible news story revealed that he was told the compromising information on Clinton was "part of Russia and its government's support for Mr. Trump."

The special counsel investigation into Russia's election meddling resulted in Manafort's indictment in November on charges of tax fraud and money laundering.
