				 After receiving 
				President Barack Obama's endorsement on Thursday to succeed him 
				in the White House, Clinton, who this week clinched the 
				Democratic nomination for the Nov. 8 election, tweeted she was 
				honored to have his support and "fired up and ready to go." 
				 
				Trump, who has made extensive use of Twitter during his 
				insurgent Republican presidential campaign, took the opportunity 
				to tweet back: "Obama just endorsed Crooked Hillary. He wants 
				four more years of Obama—but nobody else does!" 
				 
				Clinton's account quickly responded: "Delete your account," in a 
				tweet to her 6.7 million Twitter followers. 
				 
				Within minutes, the phrase, a popular form of online dismissal, 
				became Clinton's most popular tweet ever, with more than 194,000 
				retweets and 213,000 likes. 
				 
				Prominent Republicans rushed to their presumptive nominee's aid, 
				taking thinly veiled shots at Clinton's use of a private email 
				server while secretary of state. 
				 
				".@HillaryClinton If anyone knows how to use a delete key, it's 
				you," tweeted Republican National Committee Chairman Reince 
				Priebus. 
				 
				Clinton has repeatedly said she chose "not to keep" some 30,000 
				emails her lawyers deemed personal, which has been widely 
				interpreted as meaning she deleted the personal emails. 
				 
				Trump later rejoined the battle, tweeting: "How long did it take 
				your staff of 823 people to think that up--and where are your 
				33,000 emails that you deleted?"
