Business Insider reports President Donald Trump followed up his summit with Russian President Vladimir Putin in Helsinki with a swift invitation for Putin to visit Washington — but it seems Putin may not be that into the idea. Kremlin aide Yuri Ushakov said Russia agrees with Trump that the leaders should meet again, but maybe not one-on-one. He said: "There are other options which our leaders can look at," like the meeting of G20 leaders in Argentina in November.
