President Donald Trump wants to investigate former Pres. Barack Obama for ""the biggest political crime and scandal" in US history."<br />Business Insider reports that Trump has asked GOP Sen. Lindsey Graham to have Obama testify about "Obamagate."<br />What is "Obamagate"?<br />"Obamagate" is a conspiracy theory that accuses the Obama admin of concocting the Russia investigation and targeting Trump officials for politically reasons.<br />Trump took to Twitter to harangue Graham, the chairman of the Judiciary committee, to call Obama to testify.<br />"He knew EVERYTHING. Do it @LindseyGrahamSC, just do it. No more Mr. Nice Guy. No more talk!"<br />Graham responded to Trump's tweet, telling Politico he will not call Obama in to testify.<br />"I don't think now's the time for me to do that," Graham said.<br />"I don't know if that's even possible. I understand President Trump's frustration, but be careful what you wish for."
