WASHINGTON – The economy, impeachment and the border wall – President Donald Trump served up some politics Monday along with a traditional ceremony at the annual White House Easter Egg Roll.

Egged on by reporters, Trump said he in no way fears impeachment over special counsel Robert Mueller's report on the Russia investigation; he also disputed accounts in the report that aides on occasion disregarded his requests.

"Nobody disobeys my orders," Trump said, though the Mueller report described more than a dozen cases of aides disregarding his orders.

In addition, Trump's public remarks to parents and children gathered on the White House lawn included a shout-out to his military policy.

And, for good measure, one of the children at the egg roll urged Trump to "build that wall."

“I will; oh, it’s happening," Trump told the child, who asked about the proposed border wall between the United States and Mexico.

Turning to adults in the area, Trump said: "Here’s a young guy who said, ‘Keep building that wall.' Can you believe that? He’s going to be a conservative some day!”

How Trump might build an extended wall remains a mystery; Congress has refused to authorize funds for the project.

Mueller's report said the investigation did not find a criminal conspiracy between the Trump campaign and Russians who sought to interfere in the 2016 president campaign. But the report listed multiple contacts between Trump associates and Russian operatives during the campaign.

The report also listed 10 episodes in which Trump may have sought to interfere in the Russia investigation, items House Democrats have vowed to investigate with a possible eye toward impeachment.

Asked by a reporter if he was worried about impeachment, Trump said, "Not even a little bit."

He also commented on the Easter terrorist attack in Sri Lanka, calling it a "terrible, terrible thing ... that's a terrible thing."

Earlier, the president, first lady Melania Trump, and the Easter Bunny stood on the South Lawn balcony as Trump addressed the crowd in what almost sounded like a campaign speech.

"Our country is doing fantastically well, probably the best it's ever done economically," he said.
