President Donald Trump kept the door open to showing up to the Russia-Ukraine negotiations that are expected to happen in Turkey on Thursday.

'I was thinking about going, but it's very tough because of what we're doing today and tomorrow. But you know, if something happened, I'd go on Friday if it was appropriate,' Trump said.

The status of the peace talks is unclear. Russian President Vladimir Putin declined to attending, sending aides and deputy ministers instead of going himself. Ukrainian President Volodymyr Zelensky is headed to Turkey but said he wouldn't attend the high-stakes talks unless Putin was there as well.

Trump - who has said Putin should make the trip - urged the leaders to come to a peace deal.

'We we have people right now negotiating, I just hope Russia and Ukraine are able to do something. It has to stop,' he said.
