(CNN) Senate Majority Leader Mitch McConnell and President Donald Trump's top lawyer sketched out a plan Thursday to coordinate closely for an impeachment trial but haven't reached agreement on a final strategy to defend Trump against charges of high crimes and misdemeanors, according to two sources familiar with the conversation.

The closed-door meeting Thursday between the Kentucky Republican and White House counsel Pat Cipollone occurred as Senate Republicans and the White House have diverged on what they would like to see take place in the looming trial in the chamber. Trump has made clear he wants witnesses to testify, in person, while senators -- including McConnell in private -- have warned that going down that path could lead to a politically precarious slippery slope in the GOP effort to acquit the President.

"We are having a lot of good conversations with Senate Republicans," Eric Ueland, the White House director of legislative affairs, told reporters as he departed the meeting with Cipollone. "We will continue to do that here over the next few days and weeks as we work through all these issues and priorities the President has outlined when it comes to where we should go on these articles."

While no final decisions have been made, McConnell and Cipollone agreed that when a trial begins, the House Democratic impeachment managers would have an opportunity to present, followed by the Trump's lawyers presenting the President's defense, the sources said.

At the conclusion of the presentations, the White House may provide its own briefing to Senate Republicans about the next steps it would want to see in the trial, including possible witnesses it would like to be called, the sources said.
