"We can't have well off nations funding terrorism", Trump said in Wednesday's interview.
Tillerson arrived back in Doha after meeting Saudi Arabia's King Salman and Crown Prince Mohammed bin Salman 24 hours earlier.
On June 23, the four Arab states issued a list of 13 demands to end the rift with Doha, including closing of the Al-Jazeera television and cutting diplomatic ties with Iran.
Le Drian stressed that the crisis must be solved by the Gulf countries themselves, pointing out that France does not want to substitute anyone as it just wants to add its efforts to other countries efforts and support the Kuwaiti mediation. Staunchly defending its innocence against the allegations from the onset of the crisis, Qatar claimed the demands were deliberately created to be impossible for it to meet and rejected them, causing the current stalemate in negotiations.More news: Warm, sunny Sunday before possible hazardous thunderstorms and showers Monday

Many analysts are sceptical about Washington's efforts to resolve the crisis between Qatar and Saudi Arabia and its allies, saying U.S. officials are not that willing to see the crisis settled soon because the perpetuation of the crisis would benefit Washington.
On Tuesday, speaking in Doha, Tillerson described Qatar as being "reasonable" in its dispute with the four states. All three are considered allies of many Western nations.
