California senator Kamala Harris, one of the leading Democratic candidates to challenge the president in 2020, has said the Justice Department would have little choice but to pursue criminal obstruction charges against Donald Trump if she were elected to the Oval Office.

President Trump has meanwhile lashed out on Twitter suggesting reports about internal polling indicating he might lose next year’s race are “Fake numbers” and the work of the “Fake (Corrupt) News Media”.

In Washington, the House Intelligence Committee is staging a hearing on lessons learned from the Mueller report while the president’s son, Donald Trump Jr, is due to appear before the equivalent Senate committee behind closed doors.

The president was meanwhile joined on Wednesday by Poland’s president, Andrzej Duda, when he announced he will send 1,000 more US service members to Poland as part of his broadening security and economic alliance.

Mr Trump said the Polish government will pay for the infrastructure to support the additional troops, and he praised Poland for increased defense spending to meeting its NATO commitments.

Earlier in the Oval Office, the president said the United States has based tens of thousands of troops in Germany for a “long, long time” and that he probably would move a “certain number” of those personnel to Poland, “if we agree to do it.”

Mr Trump also said Poland is buying more than 30 F-35 Joint Strike Fighter jets from the US. In recognition of that purchase, a single F-35 flew over the White House on a sunny afternoon. Mr Duda looked up and waved as the jet passed.

“They’re going to put on a very small show for us and we’re doing that because Poland has ordered 32 or 35 brand new F-35s at the highest level,” Mr Trump said.

US officials also said earlier this week that Mr Trump, in addition to the additional troops, would send a squadron of Reaper drones to Poland to aid its self-defense amid concerns about Russian military activity.
