US President Donald Trump is considering firing Deputy Attorney General Rod Rosenstein, CNN reported on Tuesday. 

The FBI raided the office and hotel of Michael Cohen who is serving as Trump's lawyer and close confidant. The decision of the raid was signed off by Rosenstein who was handpicked by Trump last year to take up as second-in-command of the Justice Department. 

Trump is also considering firing Attorney General Jeff Sessions, but Rosenstein remains the main target, according to CNN. 

Rosenstein, a veteran Republican prosecutor, appointed Robert Mueller to lead the probe looking into Trump's alleged ties between Russia and the Trump campaign. 

On Tuesday, US Senate Minority Leader Chuck Schumer warned President Trump that firing Rosenstein would spark a "constitutional crisis." 

Many, including Republican lawmakers and Trump's advisors have also warned the president on removing Mueller as the special counsel to the Justice Department.
