There are several claims to be addressed in that tweet:
1. Hillary Clinton is crooked.
The definition of "crooked" is unclear. One particular definition would require Hillary Clinton to be guilty of some specific crimes beyond reasonable doubt - for that particular definition the claim is false. Another definition of crooked merely requires Hillary Clinton to be dishonest, which - as with most public figures - is subject to debate. Yet another definition only requires her to be a professional politician, in which case it is true.
2. Hillary Clinton destroyed phones with a hammer.
Hard to prove, there is no evidence she personally destroyed a phone with a hammer, and no evidence otherwise. Some of her phones were physically destroyed on disposal, so this is likely a misrepresentation of something else, which I'll get to in the implicit claims. Also, I'm adding "destroy phone with a hammer" to my bucket list.
3. Hillary Clinton bleached emails.
Probably no, considering that emails cannot be bleached. "Bleached" might be intended as a stand in for a series of verbs, such as "deleted", "wiped any trace of", or "attempted to wipe any trace of". Depending on the exact meaning of "bleached" this statement could be true or false. Because we can't know the intended meaning of "bleached", the truthfulness of this statement is unclear.
4. Hillary Clinton had Bill Clinton meet with Loretta Lynch.
Unproven. Bill Clinton and Loretta Lynch did meet, but there is no evidence this happened on Hillary Clinton's request. The source of this claim is Donald Trump, but he himself was unsure at the time, and offered no evidence. His tweet was "Bill's meeting was probably initiated and demanded by Hillary,". This new information lacks the "probably" of his initial claim, so unless Trump gained additional information this is just a guess.
1. Hillary Clinton and/or affiliates destroyed phones with a hammer, thus destroying evidence.
This seems to be a misrepresentation of the fact that phones were destroyed after migrating data to a new phone, as outlined by BobTheAverage's answer. Destroying a device after migrating data is not usually destruction of evidence.
2. Hillary Clinton and/or affiliates deleted emails to destroy evidence.
Unproven, although debatable. The story about how some emails were deleted involves a sufficient amount of details and incompetence to be either completely believable or completely made up, depending on the observer's point of view.
3. Bill Clinton met with Loretta Lynch in order to successfully obstruct the email investigation.
The obstruction part is unproven, and the "successful" part seems to be false, considering that the way the investigation was conducted cost Hillary Clinton the Presidency with a reasonable level of confidence.
4. People who talk about obstruction of justice in the Trump case are Hillary Clinton supporters.
This is most likely false given that at least one poll claims a quarter of Republicans think Trump tried to obstruct or impede the Russia investigation.
5. If Hillary Clinton commits a crime, it is legal for Donald Trump to commit a similar crime.
This is false.
For completeness, let's also rate the claim this tweet responds to:
- Donald Trump committed obstruction of justice in some of his interactions with James Comey.
Unproven, although debatable. If we assume Comey's account of the events is untrue then we can assume the claim is false. If we assume Comey's account of events is true, then it's a matter of which law professor you ask.
