A MOST DISHONEST TWEET: Sayeth Sen. Claire McCaskill (D-MO) on Twitter:

I’ve been on the Armed Services Com for 10 years. No call or meeting w/ Russian ambassador. Ever. Ambassadors call members of Foreign Rel Com.

When caught, McCaskill claimed that there was insufficient room in the 140-character limit to add 'one-on-one' (1-1) before the word 'call' in the tweet. Except that the tweet itself is 142 characters (count 'em).
