Washington: Deputy Attorney General Rod Rosenstein, who appointed Robert Mueller to investigate alleged Russian collusion in the 2016 presidential elections, tendered his resignation on Monday.
Rosenstein, who wrote a letter to the White House, will serve in his current capacity till May 11, according to media reports.
"I am grateful to you for the opportunity to serve; for the courtesy and humour you often display in our personal conversations; and for the goals you set in your inaugural address: patriotism, unity, safety, education, and prosperity because 'a nation exists to serve its citizens'," Rosenstein wrote in his letter.
"We enforce the law without fear or favour because credible evidence is not partisan, and truth is not determined by opinion polls," read the letter cited by media. "We ignore fleeting distractions and focus our attention on the things that matter because a republic that endures is not governed by the news cycle," it added.
