The physical location of the president doesn’t matter.
Anywhere he is, he has access to secure communications to get information and to discuss things with his people. So he is able to perform his work.
He doing most of the heavy lifting himself. He deserves a huge vacatiin.
{Had a very good phone call with @EmmanuelMacron, President of France, he tweeted Friday, describing it as just one of many other calls and conversations, including a dinner with Apples Tim Cook.
...Hes hosted several donor events, including a dinner for Protect the House, a fundraising committee led by Vice President Mike Pence and House Majority Leader Kevin McCarthy that raises money for Republican House candidates.
On Tuesday evening, he welcomed more than a dozen CEOs, their spouses and staffers for an animated dinner that included frank discussions of trade, immigration and other issues.
...Trump does meet with staff and has been speaking by phone with Pence, his secretary of state, his national security adviser and congressional leaders.}
From their article - doesn’t sound like much of a vacation to me.
