Live updates: Donald Trump’s hush money trial

Trump’s legal team signaled ahead of the hush money criminal trial that they would attack the veracity and completeness of the information on Michael Cohen’s electronic devices — part of a broader strategy to chip away at the credibility of a key witness.

Before the trial began, Trump’s team tried to subpoena the Manhattan district attorney’s employee who was responsible for the phones during the four-day lapse before delivering the devices for review by the department of Douglas Daus, the man who we’ve been hearing testify.

Trump’s lawyers indicated in the letter they wanted to “challenge the integrity of evidence DANY will seek to offer from Cohen’s phones, for use in cross-examination of Cohen” and “regarding the bias and hostility toward President Trump to attack the lack of integrity of DANY’s investigation under federal constitutional.”

Prosecutors have sought to push back on this angle from the defense in court today.

“Did you see any evidence of tampering or manipulation on any of the data that you pulled related to the recording that’s in evidence as people’s 246?” prosecutor Chris Conroy asked a short time ago.

“I did not,” Daus testified.

Remember: Cohen, Trump’s former personal lawyer and “fixer,” served federal prison time for actions he took while playing that role. Now he is a key prosecution witness who will testify later in the case.

Several witnesses have already testified to unsavory things about Cohen, and the defense has been highlighting his past wrongdoing in hopes of chipping away at his credibility before he takes the stand.
