(CNN) - Is Donald Trump once again thinking about making a run for the White House?
The real estate mogul and reality TV star has been invited this year to more than a dozen Republican party or conservative political events, and the campaign research Trump spent $1 million on in 2011 remains relevant, a top Trump spokesman told CNN Monday.
Trump, who flirted with runs for the Republican presidential nomination in the 2000 and 2012 cycles, already spoke in March at the Conservative Political Action Conference. The event, which is the largest annual gathering of conservative leaders and activists, is considered a must attend cattle call for Republican presidential hopefuls. And next month Trump addresses social conservatives at the Faith & Freedom Coalition's "Road to Majority" conference in the nation's capital.
Last week Trump, who turns 67 next month, spoke in front of what's being touted as a record crowd at the Oakland County, Michigan Republican Party Lincoln Day Dinner.
"Everybody tells me, 'Please run for president. Please run for president.' I would be much happier if a great and competent person came along," Trump told attendees, according to local press reports. "I'm a Republican, but before anything, I love this country. I would love to see somebody come in who is going to be great."
Trump's research was conducted in 2011, for the 2012 election, Michael Cohen, his executive vice president and special counsel, tells CNN. He explains that the research, broken down state by state, was a very detailed analysis of what Trump would need to do get on the ballot in each state as a Republican, and what he would need to do to win.
Cohen says the research, which has been sitting on his bookshelf since late spring of 2011 when Trump decided against running for president, remains relevant for a 2016 race "because almost all the same players are involved."
Cohen says that "you don't spend a million dollars to adorn a bookshelf," adding that Trump "didn't commission the research for nothing."
Cohen also mentioned that if Trump launched a campaign for president, he would be required to turn over control of his businesses to his children, or to a trust.
