Ukrainian President Volodymyr Zelensky told CNN on Saturday that he's "ready for [the] next call with Mr. Trump" if working with the U.S. and the president will help his country.

Why it matters: The July 25 call between Zelensky and Trump led House Democrats to launch a formal impeachment inquiry, after a whistleblower complaint from the intelligence community alleged that Trump "sought to pressure the Ukrainian leader to take actions to help the President's 2020 reelection bid."

Flashback: In December, Zelensky publicly pushed back on Trump for withholding military aid last summer while his country was at war with Russia.

  • Trump confirmed that he withheld almost $400 million in aid.
  • Democrats sought to charge the president with abuse of power and obstruction of Congress over accusations that he withheld that aid to solicit election interference from a foreign country.
  • Sen. Lamar Alexander (R-Tenn.) said earlier this month that he believed Trump withheld aid to Ukraine to "encourage" its government to investigate the former Vice President Joe Biden and his family. He voted to acquit Trump because he believed any consequences for the president's actions should be decided in the next election.

What to watch: Ukrainian Deputy Prime Minister Dmytro Kuleba told reporters in December that his country was still working to schedule a White House meeting for Zelensky.

Driving the news: The risk advisory firm DNV GL, citing the pandemic's long-term effects on energy consumption, projects in a new analysis that global CO2 emissions "most likely" peaked in 2019.

The U.S. economy added 4.8 million jobs last month, while the unemployment rate dropped to 11.1% from 13.3% in May, according to government data released Thursday.

The state of play: While the labor market showed more signs of recovery when the government’s survey period ended in early June, the lag means that more recent developments, like the surge in coronavirus cases and resultant closures in some states, aren't captured in this data.

Another 1.4 million Americans filed for unemployment last week, the Department of Labor announced Thursday.

Why it matters: New applications for unemployment remain historically high, suggesting layoffs are still widely prevalent. However, they remain well below the all-time record seen when the coronavirus pandemic first hit.
