President Trump for the first time is acknowledging that the Justice Department is investigating him as part of its widening Russia probe. Washington bureau reporter Alberto Pimienta filed the following report.

President Trump is a prolific Twitter user. So it was no surprise that it was on Twitter Friday that he made quite a revelation.

The White House is staying silent, referring all Russia questions to the President’s personal attorney. 

In the same tweet, the commander-in-chief seems to criticize Deputy Attorney General Rod Rosenstein. Senators are now sounding the alarm.

In a statement, the ranking member of the Senate Judiciary Committee, Democratic Senator Dianne Feinstein saying she is "growing increasingly concerned" that the president will try to fire Mueller and Rosenstein. 

The senator added, "If the president thinks he can fire Deputy Attorney General Rosenstein and replace him with someone who will shut down the investigation, he’s in for a rude awakening."

And in Little Havana, in Miami, the president announced changes to the Cuba policy of the previous White House. 

"Easing of restrictions on travel and trade does not help the Cuban people. They only enrich the Cuban regime," Trump said.

The administration will require Americans who want to visit the island to be part of a travel group run by American companies. Those groups have to legally fit 12 categories to justify their travel, blocking Americans from embarking on solo trips. 

The administration is also banning all transactions with enterprises run by a corporation linked to the Cuban military deeply involved in all aspects of the island's economy. That company owns dozens of hotels and restaurants. 

"The profits from investment and tourism flow directly to the military. The regime takes the money and owns the industry," Trump said.

The Treasury Department has to issue new regulations to make the changes official, so Americans traveling to Cuba soon won't be affected.
