Tian Tian, the UK's only female giant panda, has conceived and could give birth to a cub as early as August. However Edinburgh Zoo, where the pandas live, have warned people 'not to get too excited' as the process is 'extremely complex'. Moreover, on the two previous occasions keepers inseminated Tian Tian - whose name means 'Sweetie' - she has failed to produce a panda cub. She was artificially inseminated again in March this year, but keepers at the zoo say implantation - when a fertilised egg attaches to the uterus - has not yet occurred.Tian Tian has conceived and could give birth to a cub as early as AugustShe has been inseminated twice before but so far failed to produce a cubTian Tian and Yang Guang arrived in 2011 from China to great fanfareOn loan at £600k a year, became first giant pandas to live in UK for 17 years

Q: Washington (CNN) Vice President Mike Pence will try to leave behind a White House in tumult when he arrives in Europe Friday, but he's likely to be dogged by the recent events that have thrown the Trump administration into disarray. Though he is seeking to reassure key allies such as Germany of US resolve on Russia and other issues that have rattled Western leaders, he himself faces questions about how much he's been looped in on President Donald Trump's thinking on the Kremlin. On Monday, Trump ousted his national security adviser, Michael Flynn, for misleading Pence about his conversations with the Russian ambassador. Pence, who had previously gone on television and repeated Flynn's prevarications, only discovered he was misinformed last Friday -- a full two weeks after Trump himself learned the Justice Department was looking into the matter.Pence is traveling abroad for the first time since taking officePence arrives in Europe at a moment of deep unease for leaders 
 Question:Instead, he's cast _ -- whom he asked to resign -- as unfairly brought down by illegal leakers of classified intelligence.
A:
Michael Flynn
