Did Ho Ching really post that monkey photo unintentionally?
We put Ho Ching's 'rude monkey' gaffe to the test and this is our conclusion
Despite her apology, some netizens continued to doubt Ms Ho Ching's claim that the photo of a monkey appearing to show a rude gesture was the result of her "playing around with Twitter".
The self-proclaimed "Twitter newbie" said that she had been "trying out different buttons, seeing what can or cannot be done".
She then added: "Discovered Twitter posts pictures, without captions, and unfortunately one of the pictures could be misunderstood on its own. Took down as soon as a friend alerted me."
The photo was posted on the same day - April 8 - Dr Lee Wei Ling made accusations about her brother Prime Minister Lee Hsien Loong.
While some netizens accepted Ms Ho's explanation, others questioned if her post was unintentional.
Facebook user Paul Chen said on a comment thread discussing the issue: "Ho Ching, so coincidental that you unintentionally posted this monkey photo at a sensitive time when your sister-in-law (Dr Lee Wei Ling) is having a feud with your husband?
"Don't insult our intelligence."
On Monday night, Ms Ho did several tests to prove how a "Twitter newbie" could re-post a Twitter photo on Facebook, with no indication that the post had first appeared on the former.
We tried it her way. What happened?
Embarrassed apologies to lovers of entertaining political drama but it appears that Ms Ho could have just committed an ill-timed, unintentional Twitter gaffe.

Other social media gaffes
British PM follows escort agency
In November 2013, it was found that British Prime Minister David Cameron was following a high-class escort agency on Twitter.
It was reported to be an accidental follow.
The Prime Minister's office explained that the account had been followed due to an automated system. "Prior to 2010, an auto-follow process was used, meaning that @Number10gov automatically followed anyone who followed the account."
Governor posts sexy photo
In 2014, Governor Jack Markell's office accidentally tweeted a photo of a woman in bondage gear while announcing a public education initiative.
Markell explained that his employee had accidentally deleted a part of the photo link and that led to the publishing of the sexy photo.
He then apologised: "Earlier photo was tweeted bc link was accidentally changed during upload, resulting in random, unrelated pic. Wish link was to cat video."
Bieber visits war shrine
Justin Bieber angered many in 2014 after visiting and paying respects to Japan's war dead at the controversial Yasukuni Shrine, and posting a photo of it on his social media accounts.
Among the dead are former military leaders from the country's imperial army who committed mass atrocities across Asia and the Pacific during World War II.
Bieber later apologised: "While in Japan I asked my driver to pull over for which I saw a beautiful shrine. I was misled to think the shrines were only a place of prayer. To anyone I have offended, I am extremely sorry. I love you, China, and I love you, Japan."
ESPN analyst tweets link to porn
In January 2015, ESPN recruiting analyst Gerry Hamilton reported via Twitter that American football player Roquan Smith had scheduled an official visit to an American university.
Instead of linking a highlights video in the tweet, he accidentally posted a link to a pornographic video instead.
