ABC News reported on Friday that Rosenstein has privately said he may need to recuse himself from matters relating to the Russian Federation probe, given that he could become a potential witness in the investigation.
Trump's digital volley appeared to be trained at Deputy Attorney General Rod Rosenstein, who recommended the firing last month of James Comey - an nearly unprecedented move that could yet imperil Trump's presidency.
The panel is conducting both open hearings and closed sessions as it investigates Russian efforts to influence last year's campaign.
A White House official said Friday's tweetstorm is a sign Trump is "taking matters into his own hands" - the latest example of how he thinks he is the best person to deliver his message. And as Rep. Ted Lieu (D-Calif.) declared in a tweet Thursday, "If Trump fired Mueller (he'd also have to fire Dep AG Rosenstein), it would be an 11 on the Richter scale of #obstructionofjustice". But Rosenstein, too, may ultimately have to hand off oversight given his role in Trump's decision to fire Comey. He also returned to attacking Hillary Clinton, who he defeated in the Presidential election by virtue of the electoral college (while losing the popular vote) by tweeting, "Crooked H destroyed phones w/ hammer, "bleached" emails, & had husband meet w/AG days before she was cleared- & they talk about obstruction?"
His comments follow a report that former FBI Director Robert Mueller is examining whether Trump obstructed justice by firing FBI Director James Comey. The Washington Post first reported the Cullen hire.
Doctors: Scalise remains critical, but 'excellent recovery' possible
The shooter was an IL man, James Hodgkinson , who had lashed out against President Donald Trump and Republicans over social media. He said doctors have turned down Mr Scalise's sedation levels enough that he has been able to respond to visiting family members.
Federal investigators are looking into meetings Kushner held in December with Russia's ambassador and a banker from Moscow, CBS News previously reported. Trump confirmed in a tweet Friday he was under investigation and appeared to take aim at Rosenstein, calling the investigation a "witch hunt".
Until the president's tweet, it was unconfirmed as to whether or not the president was officially part of Mueller's investigation.
A source on Trump's legal team claimed the president was referring to a Washington Post story "from the other night" rather than confirming he is being investigated.
Comey also testified Trump had directed him to drop a related FBI investigation into former national security adviser Michael Flynn.
ABC notes that, at this point, Rosenstein has "privately acknowledged" that he might eventually be called at a witness in the investigation, largely because he penned the memo that led to former FBI Director James Comey's firing. Mueller is now leading the investigation into whether Russian Federation interfered in the 2016 presidential election.
Coats met behind closed doors for more than three hours Thursday with the Senate intelligence committee, which is conducting a separate investigation into Russian interference in the election. Comey later revealed that he orchestrated a disclosure of details about conversations with Trump to prompt the appointment of a special counsel. "This investigation is so important to our country that it was incumbent on Rosenstein to find someone who would be beyond question or reproach".
