It called for the release of protesters and opposition leader Alexey Navalny.
This is the fifth day of the administration of President Joe Biden and Vice President Kamala Harris.
Trump has left a note in the Oval Office for Biden, ABC News has learned.
The content of the note is not clear at this time.
The development comes after Biden's communications director told ABC's "Good Morning America" that Trump still hadn't made direct contact with the president-elect.

Biden, a devout Catholic and the second to take the presidency, is starting Inauguration Day with Mass at the Cathedral of St. Matthew the Apostle in Washington, joined by the top congressional leaders.
House Speaker Nancy Pelosi -- another devout Catholic -- outgoing Senate Majority Leader Mitch McConnell, Senate Minority Leader Chuck Schumer and House Minority Leader Kevin McCarthy joined Biden for the service, along with his wife, Jill Biden, Vice President-elect Kamala Harris and her husband Doug Emhoff -- the nation's first second gentlemen -- Biden extended invitations to top congressional leaders. In a show of unity, all accepted those invites.
Joint Congressional Committee on Inaugural Ceremonies Chairs Sen. Amy Klobuchar, D-Minn., and House Majority Leader Steny Hoyer, D-Md., were also in attendance.
Faith has played a significant role in Biden's life -- when he lost his wife Neilia and young daughter Naomi in a horrific 1972 car accident in which his young sons Beau and Hunter were severely injured. Beau died of a brain tumor in 2015 at age 46.
An Irish violinist will play and soprano Renee Fleming will sing "On Eagle's Wings" - the Catholic hymn Biden said his son loved and which he quoted from in his November victory speech.
With the trappings of a Trump rally on a cold and windy morning, President Trump arrived at Joint Base Andrews in Maryland just after 8:30 a.m. on Biden's Inauguration Day to once again try to rewrite the history of the last four years.
A military band played "All Hail the Chief" as Trump walked onto a small stage, lined with American flags, and up to a lectern bearing the presidential seal. He first praised his own family -- whom he put into positions of power, breaking with presidential norms -- and singled out first lady Melania Trump -- known for her privacy -- to say a few words.
"Being your first lady was my greatest honor. Thank you for your love and your support. You will be in my thoughts and prayers," she said.
Trump ticked off his accomplishments, spoke about the pandemic in past tense and predicted a boom in the stock market in the coming weeks, before offering a warning of the new administration -- without ever mentioning Biden's name.
"I hope they don't raise your taxes," Trump said, "but if they do, I told you so!"
He later added, "I wish the new administration great luck and great success. I think they'll have great success. They have the foundation to do something really spectacular."
"So just a good-bye. We love you. We will be back in some form," Trump vowed. "Have a good life. We will see you soon."
Trump is now headed on Air Force One to his resort in West Palm Beach, Florida, for the final time as president.
President Trump departed the White House for the final time as president -- leaving embattled, twice-impeached and with his lowest approval rating in his four years in office.
Trump, in a black suit with a white dress shirt and trademark red tie, alongside outgoing first lady Melania Trump, in a black dress and coat, walked out on a red carpet before Trump briefly spoke to reporters and, for one last time as president, boarded Marine One, to depart the White House.
Trump told reporters the presidency was a "great honor" and an "honor of a lifetime" and that he just wanted to walk over and say "goodbye," adding "hopefully it's not a long term goodbye."
Trump's unconventional, norm-busting approach to the country's institutions -- that will likely outlast the one-term leader and leave a transformative and divisive legacy in Washington -- continue on Biden's Inauguration Day.
He is not greeting the incoming president on the North Portico and joining him to the Capitol, as is tradition, but leaving town early for his Mar-a-Lago Resort in West Palm Beach, Florida, while he still bears the title as president and the aeronautical resources the office provides.
Marine One took a final lap over Washington -- including the Capitol, where Biden’s inauguration preparations are underway.
As Trump continues to refuse to accept the election results, he has also refused to make contact with the incoming president, despite the Biden's staying across the street Monday night in Blair House -- far from the warm welcomes given by previous presidents to their successors, no matter the party lines.
Vice President Mike Pence will not appear at Trump's departure at the White House, nor his "military-style send-off" at Joint Base Andrews. The outgoing vice president is scheduled to attend Biden's inauguration.
Though hours remain in his president, Trump hasn't heard the last of Washington either as he still faces a second impeachment trial in the Senate.
