Secretary of State Mike Pompeo will make his first trip to Ukraine this week to "reaffirm U.S. support for Ukraine’s sovereignty and territorial integrity” as the country works to end a six-year military conflict with Russian-backed separatists, according to the State Department.

Why it matters: Allegations that President Trump withheld desperately needed military aid to Ukraine to pressure its government to investigate his political rivals have led to his impeachment for abuse of power. The Senate is expected to hold a trial in January.

Between the lines: Bill Taylor, the top U.S. diplomat in Ukraine who testified in the impeachment inquiry about his concerns over Trump's pressure campaign, has been instructed to leave his post in Kiev before his tenure expires, per AP.

  • The Wall Street Journal reports that Taylor is being made to leave his position shortly before Pompeo’s arrival so that the secretary can avoid meeting or being photographed with the ambassador.

The backdrop: Pompeo appointed Taylor as acting ambassador after Marie Yovanovitch was ousted from the post following a smear campaign led by the president's lawyer Rudy Giuliani and conservative columnist John Solomon.

  • Taylor’s tenure by law could have lasted until mid-January. His sudden departure has prompted complaints from lawmakers who say it could damage relations with Ukraine and send a poor message to career diplomats.

The second jobs apocalypse

This week, United Airlines warned 36,000 U.S. employees their jobs were at risk, Walgreens cut more than 4,000 jobs, Wells Fargo announced it was preparing thousands of terminations this year, and Levi's axed 700 jobs due to falling sales.

Why it matters: We have entered round two of the jobs apocalypse. Those announcements followed similar ones from the Hilton, Hyatt, Marriott and Choice hotels, which all have announced thousands of job cuts, and the bankruptcies of more major U.S. companies like 24 Hour Fitness, Brooks Brothers and Chuck E. Cheese in recent days.

As tech's giants prepare to face off with antitrust enforcers this summer, they will draw support from an array of predominantly right-leaning defenders ranging from influential former government officials to well-connected think tanks.

The big picture: The Justice Department, the Federal Trade Commission and the states have multiple investigations of monopolistic behavior underway targeting Facebook and Google, with other giants like Amazon and Apple also facing rising scrutiny. Many observers expect a lawsuit against Google to land this summer.
