[EX Q]: President Trump on Friday called  the wife of Sen. John McCain  the Arizona Republican who was hospitalized this week as he battles brain cancer   the White House said.
An official said Trump spoke by phone with  Cindy McCain  on Friday afternoon to âcheck in on Sen. McCainâs condition.â
 McCain   81  was diagnosed with brain cancer in July. On Wednesday  his office said he had been admitted to the hospital.
â Senator McCain  is currently receiving treatment at Walter Reed Medical Center for normal side effects of  his  ongoing cancer therapy â  his  office said. âAs ever   he  remains grateful to  his  physicians for their excellent care  and  his  friends and supporters for their encouragement and good wishes.  Senator McCain  looks forward to returning to work as soon as possible.â
âOf course we all wish for  Sen. McCain  to have a great health for as long as possible â Sen. Rob Portman  R-Ohio  said Friday on Fox News. âMy sense is that everybody's made a commitment to be there next week. And we will certainly be able to have the vote. Our prayers go to him and his family.â
 McCain  isnât the only Republican senator with health issues. Mississippi Sen. Thad Cochran had a procedure this week to remove a non-Melanoma lesion on his nose  his spokesman said.

[EX Q]: Wa Lone  31  and Kyaw Soe Oo  27  were detained on Dec. 12 after they had been invited to meet police officers over dinner. Family members have said the two told them they were arrested almost immediately after being handed some documents by the officers they had gone to meet.
“They arrested us and took action against us because we were trying to reveal the truth ” Wa Lone told reporters as he and Kyaw Soe Oo were led out of the court and back to Yangon’s Insein prison after the 30-minute hearing.
In the court  Kyaw Soe  Oo  embraced  his  wife and held  his  daughter for a couple of minutes.  His  daughter began to weep as  he  was escorted away and  he  had to hand her back to other family members.
Wa Lone’s wife gave  him  a few small pieces of cake that she had brought.

Distraught relatives of  Kyaw Soe  Oo wailed and reached out to grasp him as the two journalists were driven away from a throng of reporters after the hearing.
“We view this as a wholly unwarranted  blatant attack on press freedom. Our colleagues should be allowed to return to their jobs reporting on events in Myanmar. We believe time is of the essence and we continue to call for Wa Lone and Kyaw Soe  Oo ’s prompt release ”  he  said.

Upset about damaging leaks of  his  calls with world leaders and other national security information   Trump  has ordered an internal investigation to find the leakers. Staffers  meanwhile  are so fearful of being accused of talking to the media that some have resorted to a secret chat app — Confide — that erases messages as soon as they’re read.
The chaos and competing factions that were a  Trump  trademark in business and campaigning now are starting to define his presidency  according to interviews with a dozen White House officials as well as other Republicans. Most spoke on the condition of anonymity to candidly discuss internal White House dynamics and deliberations.
Staffers buzz privately about who is up and who is down  with many eagerly gossiping about which poor colleague gets an unflattering portrayal on NBC’s “Saturday Night Live.” For the past two weeks  it has been White House press secretary Sean Spicer. But aides said  Trump  was especially upset by a sketch that cast White House chief strategist Stephen K. Bannon as the Grim Reaper manipulating the president — who was ultimately relegated to a miniature desk  playing dolefully with an expandable toy.

On Monday afternoon  as speculation of a staff shake-up was rife on cable news channels   Trump  made clear to a small group of reporters what  he  thought of  his  chief of staff: “Reince is doing a great job. Not a good job. A great job ” the president said.
The problem:  Trump  had yet to weigh in  and aides and advisers were loath to take sides without knowing for certain whether their often mercurial and erratic boss wanted to keep Flynn or cut him loose.
On Monday  after  Trump  made it through a joint news conference with Canadian Prime Minister Justin Trudeau without being asked about Flynn  a group of reporters gathered outside Spicer’s office for more than 80 minutes. Spicer twice declined to answer questions about Flynn. When White House chief of staff Reince Priebus walked by  he was asked whether the president still had confidence in Flynn. Priebus gave no answer.
Not long after  Kellyanne Conway  the counselor to the president  said  Trump  had “full confidence” in Flynn. Yet a few minutes later  Spicer issued an official — and conflicting — statement  saying  Trump  was “evaluating the situation.”

In an administration where proximity to  Trump  is power  aides  advisers and visitors often mill about in the West Wing  lingering long after their scheduled appointments have ended.

Christopher Ruddy  a longtime friend of  Trump ’s who on Sunday publicly criticized Priebus in television and print interviews as being “in way over his head ” received calls from both the chief of staff and Jared Kushner — Trump’s son-in-law  senior adviser and enforcer — and said Monday that he thought the White House was working to remedy its challenges.
 Trump ’s legislative affairs team — headed by Rick Dearborn and Marc Short  both veterans of the Hill — is also considered well-liked  disciplined and professional. But congressional staffers say they have been given advance notice about some executive orders on topics such as cybersecurity and Guantanamo Bay that have never materialized  a delay they attribute to chaos within the West Wing.
