Mueller is also examining whether there was any effort to obstruct his investigation.
The President also attempted to the put the probe beyond the legal and judicial ambit into the political orbit, asking, "Is this Phony Witch Hunt going to go on even longer so it wrongfully impacts the Mid-Term Elections, which is what the Democrats always intended?"
The Wall Street Journal reported on Monday that due to "frequent interruptions on national-security matters" and the president's "loquaciousness", it took Trump four hours to get through just two questions preparing for the potential sitdown with Mueller.
Trump also said in his series of Monday morning tweets that the investigation "is rapidly losing credibility" after the Republican-controlled House Intelligence Committee in April concluded - prematurely, according to Democratic lawmakers - that there was no collusion between the mogul's presidential campaign and the Kremlin.
The partisan political battle is seemingly headed for legal and constitutional challenges in courts that are themselves politicized to a large degree.

Real, without a hobbled Ronaldo after the break, equalised again through Gareth Bale and couldn't find a late victor . Luis Suarez took the lead at the 10th minute after he received a fabulous cross from Sergi Roberto .
Although significant portions of the released memo were redacted, one broad aspect of Mueller's scope included investigating whether Trump's former campaign manager, Paul Manafort, "committed a crime or crimes by colluding with Russian government officials" or "committed a crime or crimes arising out of payments he received from the Ukrainian government before and during the tenure of President Viktor Yanukovych".
Trump also suggested special counsel Robert Mueller's investigation into possible collusion between his campaign and Russian Federation was politically motivated.
"That's what you're really interested in", Ellis added.
The team pursuing the Russian Federation probe had provided the questions to Trump's attorneys, headed at the time by John Dowd, with the aim of convincing them to allow Mueller to question the president, something that the two sides have been discussing for months.
We know first-hand that censorship against conservative news is real. Peter Nicholas reports that Trump's lawyers argue that being forced to testify "would be a serious distraction to his work as president". In previous cases, notably involving Richard Nixon in the Watergate, the Court has ruled that the President has to submit to subpoena unless the matter involved national security. Democrats taking control of the House could lead to his impeachment.
