After US expectations were dashed this week for a transition of power in Venezuela, President Donald Trump is urging caution among senior advisers moving forward and expressing frustration that some aides are more openly teasing military intervention, according to officials familiar with the matter.

After a phone call with President Vladimir Putin on Friday, Trump also downplayed Russia's involvement in Venezuela, contradicting claims from top Trump administration officials that Moscow continues to prop up the regime there. He termed the talks "very positive".

It amounted to, at times, a picture of a President at odds with the officials who this week have called vociferously for a change in power in Caracas and have consistently declined to rule out a US military intervention.

Trump has become frustrated this week

as national security adviser John Bolton and others openly teased military options and has told friends that if Bolton had his way he'd already be at war in multiple places.

Trump has long stated that "all options are on the table" when it comes to Venezuela, where embattled President Nicolas Maduro is clinging to power despite street protests and withering US sanctions. But aides have appeared to lean further into military options in recent days as an uprising led by opposition leader Juan Guaido, whom the US recognizes as the country's legitimate president, has failed to topple him.

Secretary of State Mike Pompeo told a Fox News interviewer that "military action is possible. If that's what's required,

that's what the United States will do." And Bolton has pressed the Pentagon for military options and told an interviewer this week the US would not allow Guaido be mistreated.

But Trump, who has until now given Bolton wide leeway to manage the situation in Venezuela, appeared more cautious this week, privately expressing concern over how solid Guaido's plans are to take power and win support from Venezuela's military.

The President's skepticism was sparked after the military uprising that Guaido and some US officials were counting on failed to gain steam — leading him to ask to questions about the reliability of US intelligence that suggested senior members of Maduro's inner circle were preparing to defect.
