House Democrats are set to launch a new phase of their impeachment inquiry on Thursday when former Ambassador Kurt Volker, until recently a top State Department representative to Ukraine, is scheduled to meet with investigators.

Then, on Friday, the intelligence community's inspector general, Michael Atkinson, is due on the Hill.

More witnesses are expected next week, all for depositions behind closed doors with members of Congress and their staff.

President Trump made building a border wall between the U.S. and Mexico a cornerstone of his 2016 presidential campaign. But when, after the election, efforts to build the wall stalled, he turned to other possible options — including constructing a trench filled with snakes and alligators — according to a forthcoming book.

President Trump held a press conference Wednesday with visiting Finnish President Sauli Niinistö, as the impeachment probe into Trump's conduct intensifies.

Three House committee chairmen threatened to issue a subpoena for the documents.

"We're not fooling around here," House Intelligence Committee Chairman Adam Schiff said at a news conference with fellow California Democrat House Speaker Nancy Pelosi.

Secretary of State Mike Pompeo has publicly acknowledged that he was listening to the July 25 phone call between President Trump and Ukrainian President Volodymyr Zelenskiy that has sparked an impeachment inquiry.

"I was on the phone call," Pompeo said Wednesday in Rome.

The Trump campaign and the Republican National Committee took in a huge haul in the third quarter, which ended Monday — a combined $125 million.

This means that this year alone, they've raised more than $300 million — double the total that then-President Obama and the Democratic Party had raised at this point in 2011 on Obama's way to a successful reelection bid.

Former Democratic Texas Rep. Beto O'Rourke said he firmly supports the House impeachment inquiry of President Trump, calling it the "right course to pursue."

He also charged that Senate Republicans are complicit in allowing the president to engage in "willful lawbreaking."
