Trump released the letter, saying it had been sent to Sen. Lindsey Graham, R-S.C., who had asked former Director of National Intelligence James Clapper in a recent Senate hearing if he had ever seen "a situation where a Trump business interest in Russia caused him concern." Clapper's answer appeared to be less than a wholesale no – he said he'd seen nothing to concern him in the investigation of Russian meddling in the 2016 election but that he couldn't answer beyond that because it could interfere with an investigation.
