Former Obama spokesman: More about Trump's Russia ties will emerge

DUBAI, United Arab Emirates -- A former White House spokesman during the Obama administration said Sunday he believes more will come to light about ties between Russia and aides to President Donald Trump.

Josh Earnest pointed in part to political consultant Roger Stone's communication with a person involved in hacking Democratic National Committee emails.

And when asked about Trump's claim, made without evidence on Twitter, that Obama ordered a wiretap on him, Earnest simply said: "The bigger the scandal, the more outrageous the tweet."

"It's undeniable that there's a lot of really good unanswered questions about why senior Trump officials are, at best, not being forthcoming about their interactions with Russians," Earnest said.

Stone "is somebody that we know, that President Trump has acknowledged, that he relies on for political advice.

"These are questions that need answered, and it's not particularly surprising to me that President Trump is looking for some colorful ways to distract from that line of questioning," he said.

Earnest, from Kansas City, Missouri, served through all eight years of the Obama administration and became his press secretary in May 2014. In that role, he had tough words for Trump, once describing his campaign as having a "dustbin of history-like quality" before speaking about White House worries about Russian meddling in the November election.

Earnest said Trump took office pledging to "break the china ... and he's looking for ways to conspicuously make good on that promise."

That includes the more hostile approach Trump and officials in his administration have taken in relation to the press, he said.

But that comes as a way to distract from questions surrounding his campaign's contacts with Russia, such as those of Stone, Earnest said.

Stone said he had a "perfunctory, brief and banal" private Twitter exchange with "Guccifer 2.0," the online persona that posted the DNC emails online.

The U.S. government later concluded the Russian government directed the DNC hack in an attempt to influence the outcome of the presidential election.

Stone's acknowledgement could pose a new headache for the White House as the FBI and the House and Senate intelligence committees investigate Russia's interference ahead of the vote.

"There's a lot more to this story to be written," Earnest said.

Earnest was in Dubai to attend the government-sponsored Public Diplomacy & Government Communication Forum. He said while he received questions about Trump, he hadn't been questioned yet about the nuclear deal with Iran.

Gulf Arab nations like the United Arab Emirates are incredibly skeptical of the deal, worried about Iranian influence spreading amid the war against the Islamic State group in Iraq and Syria. Earnest said the deal and its requirement of ongoing verification "enhanced the national security of our partners here in the Gulf."

"While our strategy may have been different than what was prioritized here, our goals were the same," he said.

Earnest spoke Sunday morning to a closed-door meeting of Emirati officials and others on "crafting key messages and holding statements." While acknowledging "the norms and traditions for political journalism are different in the UAE than they are in the United States," he said his visit and events like the forum could only help.

"It's an opportunity to talk to people here about how much our country benefits from government communication professionals being interested in engaging with independent journalists," he said.
