PROBLEM: Washington (CNN) Cuban Foreign Minister Bruno Rodriguez Parrilla said today that the United States has provided no evidence for its claims that US diplomats in Havana have come under deliberate sonic attack  and raised the question of whether the Trump administration is using the diplomats' injuries to unwind recent progress in creating closer ties.
"There is no evidence  there is no evidence whatsoever  of the occurrence of the alleged incidents or the cause or origin of these ailments reported by US diplomats "  Rodriguez Parrilla  said today in Washington. "Neither is there any evidence suggesting that these health problems have been caused by an attack of any sort during their stay in Cuba."
"These health problems are being used as a pretext of a political character ... to harm bilateral relations "  Rodriguez Parrilla  said at a press conference at the National Press Club. "The US government should stop politicizing this issue."
 The Cuban minister  said that the United States hasn't provided  his  government with any proof to substantiate President Donald Trump's statement that Cuba is to blame for medical problems suffered by more than 22 US diplomats and family members  some of whom have reportedly suffered brain injuries.
 Rodriguez Parrilla  also slammed Trump for  his  rhetoric about the island nation  citing the "repeated disrespectful and offensive statements on Cuba by the US president." Trump's rhetoric is responsible for "re-launching the hostile rhetoric of the periods of sharpest confrontation "  he  said.
 He  added that anyone who claims the diplomats' health problems are the result of an attack is "deliberately lying."

PROBLEM: and Sen. Ted Cruz -LRB- R-Texas -RRB- , who trailed right behind the frontrunners in the Republican and Democratic primaries , will debate each other and field questions from audience members in a town hall on CNN . 
CNN 's Dana Bash and Jake Tapper -- who questioned Republican primary candidates like Cruz during a debate in 2015 -- will moderate Wednesday night 's debate at 9 p.m. ET . 
The two senators diverge dramatically on the ideological spectrum , with Sanders describing himself as a "democratic socialist" and Cruz often seen as a staunch conservative . 
While Sanders has vilified rich corporations for their alleged greed , Cruz advocated for more than halving the corporate tax rate in September . 
According to Reuters , Cruz sought a 15-20 percent tax rate , similar to proposals issued by Trump and much lower than the current 35 percent rate . 
Cruz has argued for eliminating the estate tax , also known as the "death tax ," while Sanders has called for a progressive estate tax structure . 
Earlier this year , CNN hosted a debate between Sanders and Cruz on health care reform .

PROBLEM: Sen. Elizabeth Warren  D-Mass.  said Thursday that the Democratic primary last year was "fair " moving away from the comments she made last week.
"I agree with what Donna Brazile has said over the last few days; that while there was some bias at the DNC  the overall 2016 primary process was fair and Hillary [Clinton] made history  " Warren  said in an interview with MassLive.
Last week  when asked by CNN's Jake Tapper if the Democratic National Committee had been "rigged" to favor Clinton   Warren  answered  "yes."

"We've got to hold this party accountable " she continued. "When Tom Perez was elected to chair of the DNC  the very first conversation I had with him was to say  'You've got to put together a Democratic Party in which everybody can have confidence that the party is working for Democrats rather than Democrats working for the party.' "
A spokeswoman for  Warren  later told MassLive that  Warren  believes  as  she  said last week  that the DNC was rigged  but that the primary itself was not.
