Donald Trump congratulated Putin on his election victory Sunday, according to a statement published on the Kremlin's official website.
Mueller has reportedly sent questions to the White House for a potential interview with Trump, though Mueller and investigators remain tight-lipped and there is no official date on when Trump might sit with investigators for an interview.
During Tuesday's White House press briefing, Press Secretary Sarah Huckabee Sanders was asked if the topic of Saudi Arabia's human rights violations came up during Trump's meeting with the crown prince.
However, any meeting between the two leaders would be controversial, given the ongoing investigations into whether the Trump campaign colluded with Russian Federation during the 2016 elections.
The president did neither, and the Post said it was unclear if Trump had even read the material.
The Kremlin spokesman says it's no big deal that U.S. President Donald Trump didn't congratulate Vladimir Putin on his re-election as president.
The Kremlin readout of the call with Trump said the two "spoke in favor of developing practical cooperation in various areas, including efforts to ensure strategic stability and combat global terrorism, with particular emphasis on the importance of coordinated efforts to curb an arms race".
Trump said he also wants to discuss Ukraine, North Korea, and Syria with the Russian leader.
What they didn't discuss today was noteworthy as well: Trump did not raise Russia's meddling in the US elections or its suspected involvement in the recent poisoning of a former spy in Britain.
"Special attention was given to considering the issue of a possible bilateral summit", the Kremlin statement said. Some world leaders have hesitated to congratulate Putin, since his reelection occurred in an environment of state control of much of the news media and with his most prominent opponent barred from the ballot. Russian Federation has denied the allegations. Trump didn't bring up the sanctions or Russia's election interference in the call, nor did he raise a nerve-gas attack on a former Russia spy in Salisbury, England, that the United Kingdom has blamed on the Russian government, White House Press Secretary Sarah Huckabee Sanders said.
French President Emmanuel Macron and German Chancellor Angela Merkel made customary calls to Putin but voiced their grievances with the Kremlin's current domestic and foreign policies.
"It's blatantly obvious that he has just an inexplicable level of support for President Putin", said Julie Smith, a European security expert who served as deputy national security adviser for former vice president Joe Biden.
