Former U.S. President Donald Trump condemned Russia's invasion of Ukraine on Saturday, switching tone from his earlier praise for Russian President Vladimir Putin just prior to the invasion to say he was praying for the Ukrainians.

Trump's remarks at the CPAC conservative gathering in Florida came hours after the United States and allies announced sweeping new sanctions that would kick some Russian banks off the main global payments systems and limit the ability of Russia's central bank to support the ruble.

Addressing an adoring crowd at an event that touts itself as the world's largest conservative gathering, Trump used his speech to bash Democratic President Joe Biden and again hint at a possible run for president in 2024.
