A$AP Rocky just got catapulted to "primary" status in the impeachment investigation of President Trump ... due to the EU Ambassador's testimony about a phone call regarding the rapper's Swedish assault case.
Rocky got roped into Wednesday's hearing because EU Ambassador Gordon Sondland said while he was sitting in a restaurant in Kiev on July 26 ... Trump called him and the "primary purpose" of their chat was A$AP.
Sondland testified Wednesday they mostly discussed A$AP's imprisonment in Sweden ... despite claims the phone call involved Trump inquiring about the Ukrainian government investigating Joe Biden and his son, Hunter.
As you'll recall, the rapper was jailed in Sweden for nearly 5 weeks as he awaited trial for assault following an altercation with a man on the street. He was eventually found guilty by a panel of judges, but with no further jail time ... Rocky bolted back to the States.
However -- pertaining to the impeachment investigation -- Sondland later testified the phone call also "included the subject of investigations" into the Bidens, and stated there was a quid pro quo established between Trump and Ukraine.
So ... not good news for the Prez, but ya gotta think Rocky's not thrilled about why his name is trending either -- especially considering his reaction Tuesday when he asked him about Trump's support.
