> The New York Post (NY Post) is an American conservative daily tabloid newspaper published in New York City.
Aside from that Wikipedia is not a good source to decide whether a publication is to be trusted due to its heavy political bias. The New York Post has a conservative bias while (English-language) Wikipedia has a heavy 'progressive´ bias as is reflected by its list of what they consider to be 'reliable/perennial sources' [1] which closely resembles a political litmus test.

There are many others, take your pick. As said these are newspapers published in tabloid format, not 'tabloid newspapers' publishing celebrity gossip and other trash although some of them do also venture in that direction on occasion.
