WASHINGTON (Reuters) - A group of former U.S. national security officials, including some who have worked for top Republicans, called Donald Trump's recent comments about NATO, Russia's annexation of Crimea and other matters "disgraceful" in a letter released on Thursday.
In the last month, the Republican presidential nominee has suggested he might not defend NATO allies if they did not spend more on defence, appeared to invite Russia to hack the emails of Democratic opponent Hillary Clinton and suggested he might accept Russia's 2014 annexation of Crimea from Ukraine.
