Donald Trump's ties with Russia have been under investigation since his victory in November. Six agencies are now looking into whether the Kremlin paid to covertly help Trump win and if he or any of his associates acted as middlemen.
The race may be over, but the investigation isn't.
Lawmakers have been making the journey to the CIA's headquarters in Langley, Virginia, to review classified information to help them assess Russia's role in the presidential election.
What they still don't really know is exactly who's been speaking to the Russians, what they've said and whether any money has changed hands.
:: The ties that bind Team Trump with Moscow
Regardless of whether or not Trump or his team have done anything wrong, the spotlight is not moving away from those questions.
Seventeen agencies agencies have already concluded that Russia tried to interfere with the US election.
Barack Obama expelled 35 Russians diplomats as punishment for what was an unprecedented hack of the DNC. Data was stolen and thousands of emails leaked.
But the story and the threat to America doesn't end there.
In Arlington, Virginia, is the cyber security firm that helped find the culprits. Dimitri Alperovtich, the co-founder of Crowdstrike, says it was a sophisticated group of actors working for the Russian intelligence agencies that breached the DNC's system.
And, he warns that they are likely still at it, seeking to infiltrate both parties.
Mr Alperovitch said: "You have to assume that both parties are being targeted. It would be frankly shocking to me if the Russians weren't trying to collect information from both sides of the political spectrum... You're talking about professional intelligence agents… military intelligence."
The ongoing controversy over links with Russia has already engulfed some of President Trump's team.
Their conversations with the Russian ambassador, Sergey Kislyak, have thrust the low profile, career diplomat into the centre of the political firestorm.
Michael Flynn, President's Trump's pick for national security adviser, is now out of a job after allegations he discussed sanctions with Mr Kislyak.
Attorney General Jeff Sessions also had to step aside from overseeing any investigation into Russia after failing to disclose he'd met the diplomat.
Tensions are high. Democrats have suggested the Republicans are incapable of conducting an independent investigation.
Republican Congressman and Chairman of the House Intelligence Committee Devin Nunes has warned against a "McCarthyism witch hunt" .
When I asked him if he would push the Trump team to disclose the nature of their conversations with Sergey Kislyak, he said "that would be highly unusual."
He also urged people not to pre-judge what he described as a "grand conspiracy" that the Russians helped elect Donald Trump.
Former US intelligence officer Lieutenant Colonel Tony Shaffer told me the investigative process needs to be "fair" and "balanced," but he doesn't think President Putin "had a grand design for one candidate or another."
"I think they just wanted to cause mischief," he added.
But there are mounting questions about the Trump team's relationship with the Kremlin. The controversy is not just about hacking, or meetings, it's about money too. There's a complex web of political and business ties, from Paul Manafort, Michael Flynn, Jeff Sessions, Rex Tillerson and Jared Kushner.
And there are still many unknowns.
The Trump administration will be keen to move on as quickly as possible from this probe. They insist they've done nothing wrong.
But their relationships have still raised doubts amongst some on Capitol Hill and Donald Trump's willingness to make a former enemy a friend, continues to create a sense of unease, even in his own party.
