The Ukrainian president’s outfit during his visit to the White House Monday reflects a change in tactics since his disastrous meeting with President Trump earlier this year.

Ukrainian President Volodymyr Zelensky joined European and NATO leaders to thank Trump — a lot — six months after the White House accused him of being ungrateful.

The White House appeared to cover up Donald Trump’s cankles in an official photo from his meeting with Ukrainian President Volodymyr Zelensky in the Oval Office on Monday. The 79-year-old president’s swollen ankles were hard to miss as his slacks crept up his shin while sitting down with Zelensky,

The White House, ahead of Monday's meeting, asked Zelensky to wear a traditional suit and tie, according to a European official and another person involved in planning. The request came through the office that handles White House protocol, though a spokeswoman declined to comment publicly.

The Ukrainian leader's visit to the White House in February ended in a heated argument. Monday's meeting with President Trump was less fraught.

Trump: “President Zelensky can end the war with Russia almost immediately, if he wants to, or he can continue to fight."

The Ukrainian leader seemed mostly upbeat about his latest White House appearance, describing his meeting with Trump as "warm". His optimism, however, appeared deliberate as he sought to avoid a repeat of his last Oval Office visit and convince his American hosts to embrace the European position on ending the war.

President Volodymyr Zelensky of Ukraine and other European leaders have learned a thing or two about negotiating, Trump-style. So has Vladimir Putin.
