Input: Consider Input: And yet , as just about everyone with internet access is now aware , Texas Sen. Ted Cruz , a Republican presidential candidate in 2016 , appeared to have liked a pornographic video on Twitter overnight . 
We do n't know for sure it was Cruz himself who did the "liking" -- as the senator explained this morning , "There are a number of people on the team that have access to the account and it appears that someone inadvertently hit the like button ." 
Below Cruz discusses the scene -LRB- that is , the one inside the court -RRB- with CNN 's Jake Tapper .

But that conversation , and others surrounding his book , did n't come close to being the first time Cruz happily discussed pornography on camera . 
In February 2016 , during the Republican primary season , the Cruz campaign posted a web video featuring an actress who had appeared in erotic films . 
Asked by some unknown interviewer about his life 's ambitions , the young Cruz pauses for effect , then announces : "Well my aspiration is to , oh I do n't know , be in a teen tit film like that guy who played Horatio . 
-LRB- Politico guessed Cruz was referencing 1986 's The Malibu Bikini Shop . -RRB- 
"It happened that one of the actresses who was there had a more colorful film history than we were aware ," Cruz told reporters on the trail . 
Cruz 's talents would send him in other directions . 
Cruz did not appear in the scrubbed campaign clip , but he has spoken -- and written -- at some length about another unlikely run-in with the adult film industry . 
This was years ago , when Cruz was a clerk on the high court for the late Chief Justice William Rehnquist . 
As Cruz recalled it in his memoir , O'Connor , Rehnquist , and their respective clerks gathered for an exhibition -- as it related to a case they were considering on the regulation of online porn -- in a small room .

Input: Consider Input: It was Petty who hired  Wallace  last October to drive  his  famous No. 43 stock car  making  him  the first black driver to race regularly at NASCARâs top level since Scott in 1971. In fact  Scott had been the only African-American to race regularly at NASCARâs top level.
When Almirola  then Pettyâs driver  was injured last season   Wallace  replaced  him  for four races  doing better in each race. Petty had hired  Wallace  before Almirola even jumped to Stewart-Haas Racing in the offseason  taking Danica Patrickâs spot.
Petty said he hired  Wallace  because of his vast potential  not his skin color. But diversity is important to NASCAR  which is trying to appeal to younger fans to fortify sagging TV ratings and live attendance. Essentially   Wallace  replaced Patrick  who wrecked Sunday in what she said would be her last NASCAR race  finishing 35th.
Patrick never finished in the top five in 191 top-series races  but  Wallace  can top that now. He received a good-luck call before the race from Hammerinâ Hank Aaron. The four-time Formula One champion  Lewis Hamilton  who is black  also tweeted his best wishes.
âLuckily I was sitting down when I was replying to him â  Wallace  said Sunday of Hamilton. âI think I was taking a golf cart ride out to an appearance and I replied back. Really cool and really special for Hank Aaron also to call right there before was really special  and just knowing that people are tuning in and hopefully noticing the new face and the new change that's coming to NASCAR and they get behind it and support it. Just exciting.â
Even before he finished third in a qualifying race Thursday   Wallace  was a popular person around Daytona.  He  then ran near the front all afternoon in a race that was splotched by three big wrecks.  Wallace  avoided them all and won a joust with Denny Hamlin to finish second.
The next race is Sunday at Atlanta  an event that is much less prestigious than Daytona. But NASCAR appears to have some traction. Dillon  27  is one of several emerging young drivers  but  Wallace  has a unusual background for a stock-car driver.  He  tweeted last year  âYouâre not going to stop hearing about `the black driverâ for years.â
On Sunday   he  said  âI'm really looking forward to Atlanta. Don't know what the hell we'll have there because it's all new for us. I know this will carry over to Atlanta and be good.â
